There are only two things you need to enter into our solar installation cost calculator: your address and the amount of your most recent electric bill.

Our calculator knows the electric rates charged by your local utility, so it can determine how much electricity you used based on how much your bill was. From here, we use information from the Energy Information Administration EIA that contains the average electric usage of a home in your area for each month of the year.

The calculator uses this to estimate what your annual usage looks like. For example, if the average customer in your area uses twice as much power in July as they do in January, then we assume you will too. These usage estimates are typically very accurate. So now that we know your electric usage, we can figure out how much solar electricity you need to cover it all.

So, for the same size house, you would generally need more solar panels in Georgia than you would in Arizona. Feel free to use our spreadsheet as a template and play around with the different items that form a solar farm: modules, inverters, power stations, trenches, manholes, roads, different types of cables and even miscellaneous things such as surveillance cameras.

Solar has been the renewable energy with the greatest cost reduction of the last decade. The reasons for this can be summarized mainly in: competitive pressures, greater installer experience, the spread of best practice installation and soft costs, module efficiency improvements and digitalization. Nevertheless, although these reasons explain the reduction of costs until now, if the curve is to keep its path downward, investing in digitalization and AI technologies is a must.
