There is no way to accurately answer this question. Too many variables come into play.
Every variable that affects your current energy bill will change that price for you. Rather than going by square footage, age of the home, insulation type and thickness, type of windows, your habits of turning off lights when not needed, whether or not your exterior doors have adequate weather stripping… It’s best take the facts you can count on.
When OTG Solar gets your past 12 months of energy use in kW hours, they know exactly how to scale your system to meet your needs. It requires your use in all 4 seasons of the year. Any other way is just a guessing game.
That said, it’s very important that you let OTG Solar know if you plan to do any remodeling (in the next few months) that will affect energy consumption before they make up your bid. Installing new windows, energy efficient appliances, and switching to LED lighting can affect your bid considerably. OTG Solar can adjust your bid based on what you have now, and what you’re switching to (easy label comparison with some basic math).
Two identical homes may require completely different systems. Without the facts of your energy use, don’t bother with a guess. It won’t be anything you can base a decision on.← Frequently Asked Questions
