These kits are specifically designed for the REC235PE US black frame panel. They are pre designed for the SMA and PV Powered inverters in almost any climate. We sell the American made SMA and PV Power inverters. The kits include everything except the regular hardware store items needed like a back-feed breaker, AC side disconnect (if needed) AC side conduit and wire. This is a kit for composition roof mount only. If you have Presidential composition (1/8” thick or more), Wood shake, tile or Spanish tile you will need to modify your order. Green Energy USA offers many different size of kits. These kits are fully customizable for different installation situations such as tile roofs, post mount or ground mounts. We are here to help the small contractor or “handy” homeowner with installation questions and sizing questions. We will gladly put you in contact with one of our listed solar installers for partial or full installs. So when you get stumped please give us a call at (661) 833-6621 and we will help you find the best solution to your install.
What size solar power system do I need for my home?This is one of the most common questions that comes up when home owners begin doing the initial research into making an investment in a grid-tie solar power system. And the answer is usually this: it depends on how much of your own power you want to produce or on how much you want to offset your monthly utility bill, depending on your reasons for choosing to install your residential solar power system. And it’s actually very easy to calculate. Just follow the the instructions below and you’ll be able to get a very good idea of what size solar power system you need.
Gather together all of your electric bills for the past 12 months and spread them before you so that you can see each one. Locate the section of the bill that gives the number of kilowatt-hours used. Write down on the piece of paper the name of the first month and the kWh used during that month. Do this for all twelve months, up to the current month. Now, add up the kWh for those 12 months to calculate the number of kilowatt-hours you used during that 12-month period. Once you have the total, devide it by 12. This will give you the avarage monthly kWh usage for your home. Next, take that number and divide it by 30. This will give you your average daily kWh usage. Now, look at the solar insolation map above and select the number that most closely matches the color in the area in which you live. For example, the extreme desert southwest of the United States is a maximum of 6.5 and the northern tier of states are a 2.5. Florida is a 4.5. Nevada is a 4 in the north and a 6 in the south. Once you have your solar insolation, or “sun hours”, number, divide your average daily kWh by the sun hours number. The resulting figure from this calculation will be the size of a solar power system capable of producing 100% of your energy needs. If you want to produce only 50% of your needs, then simply divide the result by 2. So, here is what it looks like for an example that has a monthly usage of 940 kWh: 940 (average monthly kWh) ÷ 30 = 31.33 (Average Daily kWh Usage) Then… 31.33 ÷ 5 (sun hours) = 6.26 Then… 6.26 × 1.43 (system losses dut to Derate Factor, etc.) = 8.96 This… 8.96 is the size of your system – if you want to produce 100% of your electricity. However, if you want to produce only 50% of your own power, you’ll need a 4.48 kW system. You’ll want to keep in mind that your usage will vary depending on the season. So you’ll use more electricity in the winter and summer months than you will in the spring and fall. But over the course of the year your usage of (and your bill) should average out to +/-0.
