Calculation of solar energy in your home needs

The calculation of average energy consumption of household

It is estimated that an average U.S. household consumes about 10,000 kWh of energy per year, but every house is different. So let's calculate the energy consumption of your household a year.

For calculate this value, you will need to pool their energy bills over the past 12 months. Look at the values of kWh per month in each account and write each of these values on a sheet of paper. Now add the 12 numbers to obtain total annual value of energy consumption.

As a matter of simple calculations, we assume the annual total power usage is 12,000 kWh (with an average monthly consumption is about 1000 kWh).

Calculating your solar power needs

Now that you know the total annual electricity needs, it must be combined with a properly sized solar panel. Note that solar panels are rated for peak power and average score, and has to find its average annual production panel.

To put it simply: a 10 kW solar array 12 000 kW / h Estimated annual production, if the panel is installed in a place like Philadelphia (the area has an average of seven hours of sunshine).

Therefore, a panel of 10 kW can be running a house that uses 12 000 kWh of electricity per year in the Philadelphia area. What are the dimensions of a 10 kW system be? Its total area would be about of 700-1000 m. ² The matrix can be composed of 48 small solar panels 210 watts each.

Two important notes:

1. Production estimated at panel may vary widely depending on the geographic location of the house and in the orientation of the panels installed.

2. Retailers often solar panels estimate the average production of a panel to sunny areas of the world as the Mojave Desert in California. It can be estimated a10 kW panel to be as many as 30,000 kW / h per year, which exceeds three times normal value (the value of 30,000 kW / h would be wrong for those living in the Mojave Desert, and wrong that those who live in a temperate zone, such as Philadelphia).

Financial aspects – costs and savings

How much money could a panel of 10 kW saved annually in electrical terms? A grid pattern of the average power tariff in the U.S. is $ 0.12/kWh. If we multiply 12 000 kWh per U.S. $ 0.12, we will have a total of $ 1,440 per year.

A commercial system of this size could cost around $ 30,000 (after all discounts and credits tributaries, including the tax credit of 30% U.S.). The system would pay for about 20 years and then start generating electricity for free. Building this system your account could save you thousands of dollars by allowing the system to pay for itself much faster.

much would it cost to power a 1000 sqft. house with a solar system to 100%. "

Including batteries at night to power.

It is common that misconception that the sizing of solar energy system is based on the size of your home. In fact, the best way to determine this look at the bill electricity. Are you looking for the number of kilowatt hours (kWh), which uses your home each month. It would be better if you could look at a bill that eventually would have a bit of "story" about it, showing its use over a year so you can have a good idea of your average energy consumption per month. If you do not have an account to leave, you can make a list of charges, calculation and amount of courage it takes to generate electricity. http://www.altestore.com/store/calculators/load_calculator/ The next factor that comes into play is the location of your home. Each site on the planet has a "value of insulation." This is the value means "sun noon "your house every day. These are the two factors that determine the size and cost of a solar home system. The addition of batteries in a system of this size can be very expensive ($ 3,000 – $ 40,000 for batteries only) and require monthly maintenance. The estimated cost of these systems would between $ 10,000 and $ 50,000 depending on usage and solar resources. If you want to have a better idea of a system to feed their own home, call your information into a calculator line. http://www.altestore.com/store/calculators/off_grid_calculator/

Consider solar heating – to heat water?

solar heating can also heat your pool water, pool etc, the amount you know about it and consider it? please tell me everything. Thanks More details will be selected as the best answer – 10 pts:)

systems solar water heating using solar power to work with your conventional water heater. The technology is well developed, with a wide range of equipment to meet diverse applications. Benefits: You can provide almost all of their hot water during the summer months and around 50% throughout the year reduces the impact on environment – the average domestic system reduces carbon dioxide emissions by about 400 kg per year, depending on the fuel replaced. Different types of system: What best suits your needs depends on a number of factors, including the roof area to the south, the existing water heating system (for example, some combination boilers are not suitable) and your budget. A competent professional installer should assess your situation and discuss with you the best configuration to meet your needs. heating solar water and home: solar water heating can be used at home or for larger applications such as swimming pools. For domestic hot water for three main components: solar panels, a heat transfer system, and a hot water cylinder. Solar panels – or collectors – are installed on the roof. They collect heat radiation the sun. The heat transfer system that uses heat to heat the water collected. The hot water cylinder stores the hot water is heated during the day and supplies later use. Is my property suitable? Preferably have 2 4m2 of southeast to southwest facing roof receives direct sunlight for most of the day. Also needed additional space to locate a bottle of water if necessary. Cost The cost of maintenance and installation of a typical flat-plate collector is built for £ 2000 – £ 3,000. Vacuum tube systems will cost £ 3500 – £ 4500. You can also adjust or build your own system. It may be cheaper but take longer time and need a certain level of skill. However, DIY jobs are not eligible for funding. solar hot water, usually come with a warranty 10 years and require very little maintenance. The annual verification by the owner and a more detailed check by a professional every 3-5 years should be sufficient (Consult your system supplier for exact maintenance

Six simple steps to estimate the cost of a solar energy system

Six simple steps to estimate the cost of a solar power system

Energy Systems Solar is not cheap. However, it is important to compare them in the context of other improvement projects for the home. The buyers of homes and realtors view a solar photovoltaic or solar water heating system and a significant improvement on the value-added-  “similar adding a deck or renovating your kitchen. Also, unlike a deck or kitchen remodel, including the gain on your energy bills.

Solar energy systems are often an injection of additional funds, as well: many government and public services through attractive financial offer from the United States the incentive to reduce initial capital costs associated with a solar energy system.

Here are some foolproof ways to estimate the cost of a solar photovoltaic or solar thermal and determine if a solar energy system makes sense for you. Let’s start with a photovoltaic Home (PV).

Step 1: Estimate the house electricity your needs

To begin, it is good to have a sense how much electricity it uses. You better point of comparison if you know how many kilowatt hours (kWh) used per day, per month, per year. Your bill for public services should include this information.

Of course, the electricity bill will also show their costs and many utilities include a graph showing how the monthly energy consumption / cost varies throughout the year. This will help you assess the highest energy consumption and how season.

Residential construction

If you are building a new house, you should estimate based application type of equipment will be installed and the Chamber of square feet. The pross call this “burden”.

To calculate the expected load, create a chart to record use watts for each device. Each unit – “if a water heater, lamp, computer, or in a refrigerator  should have an identification plate showing its power. Or you can get information from the manufacturer’s website.

Some amps and voltage of the list only label to reach watts multiply the two together (amperage Watts = Voltage x). In another column, record the number of hours each device is intended to operate. After many hours and watts to estimate the watt-hours of use per day. As it is difficult to foresee all electric charges (can be a problem at all tedious exploration toothbrushes and a portable charger), you can add a multiplier of 1.5 sure.

Step 2: Predicting the Future

In 2005, average electricity prices Residential United States ranged from 6 to about 16 cents per kilowatt-hour depending on where they lived. The average retail electricity and trade have increased by about 30% since 1999 and the upward trend should continue, especially overhead costs for coal and hydropower to generate electricity and to increase. So think about your electricity needs of the house and the present and future costs by over another.

Step 3: How much sun do you get?

The Florida Solar Energy Center has conducted a study to examine how a system of 2 kW photovoltaic would if installed on a very efficient energy through the area Continental United States ( http://www.fsec.ucf.edu/en/publications/html/FSEC-PF- 380-04 /).

The study accounts for all factors affecting the performance of a photovoltaic system, such as the effect of temperature PV cell, the number of hours of peak sun in different regions, and the efficiency of inverter to convert the energy sunlight from DC to AC.

Since the study implies, solar photovoltaic systems work anywhere in the United States. Even in the North or in “rainy Seattle”, a photovoltaic system can pencil if designed and installed properly. In New York, or New Jersey, a one kilowatt system should produce about 1270 kilowatts of electricity per year, in Seattle, a system should kilowatt produce about 1200 kWh per year. In the Southwest, of course, these reports are much higher.

Solar contractors in your area can help determine the ideal size for your solar photovoltaic system.

Step 4: Size your system

In general, solar photovoltaic systems sized between 1 and 5 kilowatts are usually sufficient to meet the electricity needs of most households. One of the advantages of network systems attached that you can use solar PV to supplement or offset some of its electricity needs, so you can size your system based on your budget and always added to the system later if needed.

In addition, as a side note, here is a golden rule to remember to help you calculate the physical space of the PV system may need: square foot yields 10 watts. Thus, in full sun, one square foot of a conventional photovoltaic panel will produce 10 watts of power. A system of 1000 watts for example, may need 100 â € “200 square feet area, according to the type of modules used.

Step 5: Know your repayments

Many states, local jurisdictions discounts, tax credits and other incentives to landowners to installation of residential photovoltaic systems and solar domestic water. To see a complete database of incentives available for the visit of renewables http://www.dsireusa.org .

At the federal level, you can enjoy a tax credit of 30% (up to $ 2000) for the purchase of a residential solar system at least until December 31, 2008.

Step 6: Run the numbers

Although the cost of a solar photovoltaic depends on the size of system you want to install, the electricity tariff, the amount of kilowatt-hours expected to generate, and the State / Rebates or tax credits that might be available, the formulas for calculating the yields are substantially the same.

For those who appreciate have the forms, the use of those listed below to make a quick estimate the approximate amount of a photovoltaic system could cost you.

Retail price for solar photovoltaic
Building Permits +
– Credit $ 2,000 federal tax
– Tax Credit for State and Local Government or refund
– Provision of utility or other incentive
= Net investment

Kilowatts of electricity generated from PV per year
kilowatt hours of use per year x
KW PV = annual energy

Annual kilowatts of photovoltaic
x type current residential electricity
= Annual $ saved

Excess annual production of PV
x $ credit applied per watt
= Annual value measurement net

Of course, a more accurate assessment can be done by a professional. Working with a contractor solar energy for size and the price system right for you. As with any major purchase, do not hesitate to ask several offers from different contractors.

Much suppliers of solar energy will provide a complete estimate. Useful information to know includes:

– Total cost for the operating system (cost Work for the design and installation costs and equipment)
– Team (Mark and model)
WARRANTY INFORMATION –
– The permit fees, if
– Taxes, if
– Federal tax credits
– State or local funds tax reductions or jurisdiction
Utility Refunds –
– Expected renewable energy certificates or credits Net metering
– Operation and maintenance cost estimates
– Projected savings

Solar Thermal (also called Solar water heaters)

Solar thermal systems capture the sun’s energy to heat water and are one of the systems the most viable renewable energy. Are used to heat hot water tanks and / or heating system. A system of solar pool heating Another type of solar thermal system designed to heat a pool or spa.

Usually, it is worthwhile to study the feasibility Economic installing a solar water heater If you have an electric water heater with utility rates of at least 5 cents per kilowatt hour and tax credits or discounts available. (It may even be worth changing a gas water heater if your costs are at least $ 8/million BTU).

The formulas for calculating the cost of a water heater plots are similar to the estimated cost for installation photovoltaic solar energy. Many solar energy professionals can help determine which system is best suited for you.

Heat your pool with solar energy

Although some provinces offer financial incentives to use energy Solar heated pool or spa, in general, using solar energy to heat your pool is a “manifesto” in a return on investment view.

The electricity used to heat a pool during the swimming season often amounts to the same amount of energy that households without-pools consume over one-year. The combination of a solar power system to produce heat for indoor with solar energy to conserve heat generated more heat can maximize the efficiency and extend your swimming season.

Most installers recommend a collection of solar energy used to heat a pool is a size of about half of square meters surface of the pool. The solar panels last 10 € “20 years and come with a guarantee of 10 years.

How long it takes to achieve balance in the cost of your solar system Power Pool depends where you live. In California or other parts of the Southwest, will have a balance in one to three years, but places like “north” as Canada, a system of solar pool heating pencils on a longer time period.

I would like a solar power plant for my house. I have no problem with these things, nor do I complain about a wind farm. "Charcoal now (about 5 km from me) pollutes every day. This is the burning of" clean " the plan, but traders seem to have found a way to hide their pollution. I can see the yellow mist being emitted from the plume of steam from cooling towers (But not the steam is supposed to be) on sunny days. I told the EPA about this place, but nothing was done. Grift and I think that bribery. Finally, wind and solar plants clean and efficient when feeding operation and requires no registration or mining.

Solar energy for hot water?

I need to set the hot water through solar energy? I had seen many sites and I get confussed! boilers, photovoltaic panels, the im lost! I do not want to look for installers is on research, I need?

There are two different systems used in solar thermal energy. First is to have collectors on the roof and glycol pumped through the lines in a heat exchanger in the tank solar. The heat exchanger heats the water inside the solar tank, and then the existing hot water heater said solar hot water storage tank. The other way is with a heat exchanger strapon heat that is connected to the existing reservoir, using a small space. So if you just take hot water for domestic use (water for showers, fountains, etc. ..), has two thermal panels, a storage tank (80 liters), copper tube in the tube glycol, a pump controller, expansion vessel, valves ball, and a check valve. do not get the complicated, forget the boilers and pv. Boilers are used in floor heating only (residential, of course). Some houses old may have gas or diesel boilers age thermal panels can be attached to use the same method that a hot water heater. Hope this helps.

The efficiency of the solar panel would replace coal?

A friend sent me an article that a company called Fraunhofer produce solar panels can achieve 41.1% efficiency. Now taking into account the fact that solar energy is not sent to work at night or during storms and very low during the winter what% think it would be necessary to establish a "majority" of our energy needs as a nation? Typos * * Now, taking into account the fact that solar energy "not" work during storms or at night and very low during the winter, what% do you think would be necessary establish a "majority" of our energy needs as a nation?

I'm with g.aidono. The efficiency of the commission is not the problem is cost. The photovoltaic panels create efficiency hovering around 14% now – when you see the numbers as high as 41%, a cell that is exotic, and not a glass-resistant metal frame and suitable for home use. But even at 14%, if the cost of $ 2 per watt, which would cost a winner in most households USA. Even with four U.S. dollars / Watt is a winner today in some places, such as providing the latest, very expensive kWh someone's account. If you panels is U.S. $ 1 watt, even without subsidies, people would be clamoring to connect the panels – for many, in fact, that could threaten the stability network, and new architectures would be necessary.
