How Much Solar Energy Will My Panels Get

Let s say on a good day you average 5 hours of direct sunlight.

How much solar energy will my panels get.

The price of solar has dropped by an incredible amount. The calculations would be like this. Us solar market insight from the solar energy industries association. Given 1kw of panels produces 1642 kwh per year in ca and 1kw of panels takes up 68 42 square feet solar panels installed in california on average produce 23 99 kwh kilowatt hours per square foot per year.

The amount of energy that solar panels can absorb and then produce is measured in kilowatts kw. Solar panels usually produce between 250 and 400 watts of power. We do more touring than camping and so we drive most every day this actually applies to stef and me. 25 000 kwh 365 1 5kwh per day 47 panels.

The actual output you see depends on factors like shading orientation and sun hours. If you take 1 5kwh as the average then you will require at least 47 panels. You need to know how many kwhs your home uses to determine the amount of kws your solar panels need to produce to offset your use. For example the standard panels produce an average of 1 1 5 kwh per day.

The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh. Multiply 5 hours of sunlight x 290 watts from a solar panel 1 450 watts or roughly 1 5 kilowatt hours per day. The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size. How much have solar energy prices fallen.

Typically a modern solar panel produces between 250 to 270 watts of peak power e g. Even a basic 40 amp converter will provide more charging than five 100 watt solar panels and it will do it night and day rain or shine.

Some people associate solar power with heat because heat is associated with lots of sunlight but if there s too much heat your solar panels may not work as effectively. You can use the table of solar power production per kw for each state above to do the same math for your state. Back in 1977 the price of solar photovoltaic cells was 77 for just one watt of power. Today it s around 0 13 per watt or about 600 times less.
