Solar/DRG FAQs

In many cases, it is cheaper to upgrade your home’s efficiency measures, thus reducing your bill, than to install a solar system. Generally, you want your home to be as efficient as possible, then investigate your solar production options.

The most important step for you as a cooperative member and homeowner is choosing a reputable, honest installer who will guide you through the sales, installation, and interconnection process, and who will be there for maintenance or repair issues. Once you’ve chosen an installer and agreed to the sales contract, they will work directly with us at Farmers EC to ensure a safe interconnection.

This is largely based on the size of the system you install. A good estimate would be $3 to $4 per watt. For example, a 10,000 watt (10kW) system might cost you roughly $30,000 to $40,000. We recommend contacting multiple installers and getting multiple quotes.

The size of the solar system should be specific to your own usage needs. You will want to take many things into consideration when choosing the size of your solar system. Contractors can help with the process, but it’s good to know how to size a system yourself.

Step 1: Contact the Cooperative and ask for a 12-month usage history. You can use this to gauge your consumption trends. Look at the usage (kWh) and the demand (kW) values for each month.

Step 2: You can use sites like PVWatts Calculator to model a system. It will give you a monthly estimate on how much a DRG system of any given size will produce based on your geo location and other variables.

Step 3: Compare the monthly kWh data from Steps 1 and 2 and customize your system to your needs.

Step 4: If the system is larger than 15 kWdc, verify that the size of the DRG system does not exceed 110% of your maximum historic demand.

Yes. Solar power systems do not produce power at all hours of the day. Even during a normal sunny day, you might have periodic cloud cover, or temporary fluctuations in usage at your home. And of course, after the sun goes down, all your electricity will still come from the grid.

Many factors go into the potential savings including system size, how much electricity you use and what time of day you use it, the overall efficiency of your system, panel location, shading issues and more. But as a general example, households using around 1300 kWh a month installing a 9-kW system might expect about a 40% reduction in the total cost of electricity.

Please read this part carefully: If a salesperson is claiming that you will no longer have an electric bill or claiming with certainty that you will experience a guaranteed reduction (i.e. “you will save 70% on your bill every month!”) it is most likely untrue. Please contact us with any questions as we are here to serve you, our members.

The answer is almost always no, it will not. Most solar systems are designed to automatically shut down if there is a loss of power from the grid, such as during a storm or a scheduled maintenance outage. This is a safety feature designed to prevent your system from sending power back onto the grid when linemen are working to restore power. There are set ups available where your home can go “off grid” but they tend to be more complex and expensive to install.

There are 2 ways to lower your bill with solar.

1) Reduce the electricity you purchase from Farmers EC – Electricity produced by your solar system will first supply your home, and your home will utilize that electricity before it pulls from the grid/Farmers EC. This utilized solar production should lower the amount of electricity you purchase from Farmers EC as compared to prior bills. You can think of this as a 1:1 rate of return, but only if you USE those kilowatt hours. Keep in mind, the number of kWh’s that you produce and use will not show up as a line item on your bill.

2) We pay you for the extra electricity you don’t use – Sometimes you may produce more electricity than your home requires. In this case, the excess electricity will be sent back to the grid, and you will be credited for the “avoided cost,” which is the amount Farmers EC would have had to pay for this energy in our normal course of business. Currently the rate is around $.06 per kWh, and this will show up under “Billing Summary” on your bill as “DG Avoided Cost.”

Your solar installer should provide you with a software application for your computer or phone where you can monitor your system and production. Your total solar production will not be reflected anywhere on your monthly bill from Farmers EC. The line item mentioned above, “DG Avoided Cost,” is not your total production, it is the excess electricity that your home did not need and sent back to Farmers EC.
