FAQs

What size system do I need?

The average residential system is around 6kW which takes up about 450 square feet of roof or ground space. As a Trade Ally Partner of Ameren, we can review your previous electric usage with your account number and determine what size solar system would be right for you. If your utility provider is not Ameren, we are able to use a simple calculation to determine the appropriate system size if you provide us with either the amount of an average monthly electric bill you are currently paying or how much electrical usage (kWh) your property uses monthly.

What is the lifespan of a solar energy system?

Our recommended panels come with 25 year production warranties and inverters come with 12-25 year warranties so you can rest easy knowing you will be benefiting from reliable solar energy well into the future. Many early solar panels are still running efficiently after 30+ years. It is very likely that the lifespan of your panels will exceed their warranty.

What happens during an electrical power outage?

If you have a grid-tied system, it will automatically shut down until the power is restored. This is for safety precautions and allows the utility company to safely make the necessary repairs. There are certain inverters and electrical configurations that would allow for backup power from a battery bank or generator in the case you would like power during an outage. If you experience multiple power outages or long durations without power it may be beneficial to look at backup solutions.

How heavy is a solar panel?

Typically the average weight addition to a structure is around 2.8psf (pounds per sq. ft.) with the solar module, racking, and wire management. Before any solar installation, a full inspection of the current roof structure and condition should be performed to ensure the additional weight load, wind load, and other factors will not harm the current structure. In addition, the areas where the solar array will be located will protect that section of the roof, extending its lifetime.

Are batteries required to store energy?

No, with a grid tied system think of your utility as being a giant battery. When you are overproducing, the energy will be sent to the utility, when you need it, they will send it back giving you credit for what you sent to them. This is called Net Metering.

Picking the right system for you is just as important as having the best panels! Enphase and Solar Edge are like two types of brains for solar panels. Enphase uses small brains (microinverters) on each panel, letting them work independently and do well even if some parts are shady. It also watches each panel closely. Solar Edge uses power optimizers on each panel and a big brain (centralized inverter) in the middle. It helps panels individually but is more traditional. Enphase might be better for tricky situations, but Solar Edge is a good balance. It depends on what you need and your budget. Talk to one of our solar experts to figure out the best fit for you! 🔗aka.solar/quote...
