When comparing solar panel options, one important metric to consider is a panel’s power rating, referred to as wattage. 400-watt (W) solar panels are above the average wattage of solar panels available today and can be a solid panel option for many types of solar projects.Continue reading
Over the past decade, home rooftop solar use has exploded around the country as home solar becomes a very popular investment. Homes and businesses across the country are transitioning away from a fossil-fueled electricity grid towards a clean energy economy, driven by a need to reduce emissions in a time of global climate change. Amidst this period of energy reform, rooftop solar panel systems for houses are taking off at a remarkable rate. It’s time to give residential solar the credit it deserves.Continue reading
When you evaluate solar panels for your photovoltaic (PV) system, you will encounter two main categories of panel options: monocrystalline solar panels (mono) and polycrystalline solar panels (poly). Both types of panels produce energy from the sun, but there are some key differences to be aware of.Continue reading
Most of the solar panel options currently available fit in one of three types: monocrystalline, polycrystalline (also known as multi-crystalline), and thin-film. These solar panels vary in how they’re made, appearance, performance, costs, and the installations each are best suited for. Depending on the type of installation you’re considering, one option may be more suitable than the others.Continue reading
Sticker shock can be real when it comes to a solar panel system: a full solar installation for an average home can cost tens of thousands of dollars! In this article, we’ll dig into why solar panels are so expensive, from equipment costs to installer margins and more.Continue reading
Have you ever wondered how much electricity you could produce from solar? In this article, we’ll walk through how to calculate the amount of solar power you could technically generate on your roof, as well as why our calculations aren’t all that helpful for any single homeowner.Continue reading
We estimate that a typical home needs between 20 and 24 solar panels to cover 100 percent of its electricity usage. The actual formula to find out how many solar panels you need can be found by the system size divided by the production ratio, divided by panel wattage.
The actual number you’ll need to install depends on factors including geographic location, panel efficiency, panel rated power, and your personal energy consumption habits. Importantly, the number of solar panels you need for your home directly impacts the price you pay for solar. While the answer isn’t always simple, we’ve put together some example cases to help you understand, at a high level, how many solar panels you need to install an effective solar array.Continue reading
