Solar Energy Product Buyer’s Guide

While Solar Energy may be one of the most cost-effective, cleanest, most-affordable forms of Renewable Energy available today; used worldwide for hundreds, if not thousands, of applications both large and small. But, in order to make sure that the Solar System that you purchase and install will deliver maximum performance and return on investment, it is important that your system, and its components be sized properly to meet your needs, location, application and budget.

If your Solar System is too small, it may not make enough of impact on your bills and electric usage to properly pay for itself. Additionally, if your solar system is too large (unless intentionally so for net-metering purposes) you will overpay, which can dramatically increase your payback period, and limit the cost-effectiveness which drew you to the Solar System in the first place. Neither of us wants either of these two possibilities to come true for you, so we offer our customers, free of charge, a complete range of Solar Energy Sizing guides, perfectly designed to help you choose the right solar system for you, or to help your solar professional size a system according to your needs and budget more easily.

There are many important factors that go into properly sizing a solar system for your home, office, cabin, farm, or other location. These factors include:

  • Solar Resources available at your location
  • Your average daily power usage (for solar electric systems)
  • Your peak power usage (for solar electric systems)
  • Your daily domestic hot water usage (for solar hot water systems)
  • Your home square footage and insulation levels (for solar hot water radient heat)
  • Your intended use for your solar energy system
  • Whether you intend to be Grid-Tied or Off-Grid (for solar electric systems)
