Pennsylvania's Original Solar Installation Experts

Preservationist of Yesteryear and Tomorrow


Solar and Zero Energy Homes

We installed our first battery system in 2004. Since then we have installed many systems. We almost always recommend a “priority loads” panel. This will keep your most important electrical devices running for 8-12 hours. Usually, this panel will have your kitchen and appliances, your heater motor, internet, some receptacles and lighting, and a sump or well pump. This will keep you safe and warm overnight until your solar system starts recharging at sunrise. Battery technology has improved dramatically. You can store hours of energy reliably, with no gas-pipes, no fossil fuel, no moving parts, no noisy motors running.

Solar Homes and Renovations

These homes go the next step in energy efficiency and comfort.  From super-insulation, daylighting, energy-efficient appliances and lighting, to active and passive solar systems for everything from space heating, water heating, and power generation, these homes cost little to heat and operate, and are quiet and bright to live in.

Rack and Pole Mounted

If your home has many dormers, hips, and valleys, skylights, shading, or just not enough usable area, we recommend ground mounts. Across the yard or meadow, concealed by landscaping or location, ground mounted systems are a favorite for us. We drill helical posts into the ground so there is minimal soil disturbance, and rake and seed when we are done. We are thoughtful and respectful of your property, and practicing our belief of treading lightly.

We build pergolas with translucent modules to allow filtered light onto your deck, patio, or pool and window awnings that will absorb the summer sun and let the winter sun penetrate.

Roof mount systems are the most ubiquitous type of solar system installation. Most residential roofs are sloped and have asphalt shingles. There are still many choices: USA vs Foreign-made products, increased efficiency modules, all-black modules, even solar shingles, and metal roofing material. Each one will have cost and efficiency differences. At SunPower, we recommend the system that is the best fit for your project rather than pushing just the brand that we sell.

We think solar is beautiful, but not everyone does. We always consider the aesthetics and architecture of your home or building, as well as function. We offer many alternatives and options.

For over 45 years, SunPower Builders has been committed to the Solar Energy Industry.

Founded in 1972, we are the original solar company based in Pennsylvania.

We have installed approximately 200 Solar Energy Systems within 20 miles of our offices in Collegeville, Pa.

Our systems are accurately designed for your specific location, look good, are built to last, and almost always produce higher than expected levels.

We provide the best combination of cost and longevity:

We care about the quality of our product, from workmanship to materials.

Our systems are well-built at a fair price.

We use only USA modules, racking, and EU-made central inverters: Better quality materials may cost a bit more, but for a 25 to 50-year investment, they are the better value.

Our ground mount installations are welded, not just bolted, we drill helical posts into 4-5’ into the ground for greater pull-out strength. and we do not have to excavate in your yard.

We care about the aesthetics, such as recommending a ground mount vs roof, keeping it at a low profile, and protecting and restoring your property.

There is no one that does a better job, has more than 200 installations within 25 miles, and has zero service calls for faulty workmanship or materials.

Our prices aren’t the cheapest, that’s not who we are, rather we consider ourselves the best value for your dollar.

If you have any questions, please feel free to call at any time.
