Which Solar Panels Should I Buy?

The most common questions that prospective solar customers ask is “Which solar panels should I buy?” That’s a tough question to answer, and arguably maybe not the most important question (more about that later).

I initially got into the solar business for altruistic reasons — save the planet and all that. The planet still needs saving, perhaps more than ever. But I quickly realized that the vast majority of customers were interested in saving money first (the planet could wait). So I am biased towards finding the most cost-effective system for customers. To that end, people want an inexpensive system that is reliable, high efficiency (especially if they have limited roof space), and looks good on their roof.

When it comes to the solar panels themselves (also called solar modules), all solar panels generate the same amount of electricity on a per watt basis. A 300 watt panel from Manufacturer A will generate the same amount of energy as a 300 watt panel from Manufacturer B. 24 panels with a 275 watt output will generate the same amount of energy as 22 panels with a 300 watt output (6,600 watts). Your appliances can’t tell the difference if they are using electrons from a super high efficiency panel or from a less expensive system. Nevertheless, there are clear cut differences among solar panels in terms of efficiency, aesthetics, cost and availability. On the other hand, some of the sales pitch distinctions are subjective, such as brand, quality, durability, and long term energy output.

To learn more about critical decision factors in purchasing solar panels for your home or business, listen to this week’s Energy Show. For those of you who have read to the end of this summary, the most important question to ask is: "which contractor will install the best solar power system for my home or business?"
