1. How long do solar system panels take to install?
For a typical residential system, installation takes about a day. Steep roofs or delicate roofing systems may take a little longer, but no more than 2 or 3 days.
2. Should I replace the roof before installation?
If your roof is in need of replacement, go ahead and have it replaced before having the solar system panels installed. If you replaced your roof recently or still have a lot of life yet, don’t worry about it. In the event you need to have the roof replaced after solar system panels are in place, they can be removed and reinstalled.
3. How are solar system panels priced?
Solar system panels are typically priced by the watt. The average wattage of a solar panel is about 250 watts.
4. How many solar system panels will I need?
Your home’s electricity demand, your current usage, and available roof area help determine how many solar system panels you will need.
5. How much will I save?
If you buy your solar system panels outright, it’s a difficult equation; you’ll have to consider net metering, system life, and how much electricity will rise. If you choose a solar lease or power purchase agreement, you can compare your usage at the price of electricity from your utility company to the price guaranteed by the third-party system owner to see how much you’ll save each month.
