Featured Reviews for Solar Power Contractors in Rockville, VA

Kilo Hollow Energy
Solar Power Contractors in Rockville, VA
Average rating: 5 out of 5 stars8 August 2023
“We are late getting this review in, but wanted to make our voice heard. We had been wanting to add solar to our house for a few years. With the announcement of the new government incentives, we jumped into it last year. We received many quotes and had appointments with several companies (some of them never showed up). We selected Kilo Hollow Energy out of Richmond, Virginia. We wanted to go with someone who was local. William (Sensitive Information Hidden), the owner, is an exceptional example of someone who cares about his business. He held our hands throughout the process, answered all of our questions and is very knowledgeable. We replaced our roof prior to the installation. Our roofing company came out after the solar installation and commented that it was the best solar installation he had ever seen. We chose Kilo Hollow Energy and we are very happy with the results”
Altenergy, Inc.
Solar Power Contractors in Rockville, VA
Average rating: 5 out of 5 stars8 August 2017
“We had AltEnergy, of Staunton, VA, install a 10 kW solar panel system, grid tie, with a ground based installation about 70 feet from the house. I also had them wire in a manual transfer switch for a future generator. The company was great to work with, very polite, professional, and did what they promised when they promised it. We are very happy with the work. Taylor worked with us throughout, and was great. The master electrician, Matt, patiently answered my many detailed questions. We've been up and running for about a month now, and getting the KW-hrs we expected. AltEnergy took care of setting up the SREC credit application, all coordination with the local power company, and the online process to allow us to track energy production day by day. Highly Recommended!”

Installing solar panels on the roof of your Rockville, VA home can help you avoid the rising cost of electricity, increase the value of your home, and reduce your carbon footprint. Solar energy is clean and renewable, and government rebates, subsidies and grants encourage homeowners to make the switch. Solar power systems can heat your home, produce electricity and provide hot water so that your home is entirely self sufficient. So whether you want to improve your home’s energy efficiency, save money, or do your bit for the environment, use Houzz to find the best solar power contractor for your needs.

What solar power systems are available?


The two main solar power systems are on-grid and off-grid. On-grid systems – also referred to as grid-tied and utility interactive – are connected to your mains power supply. If your Rockville, VA home produces more energy than it uses, your meter goes down and you generate credits with your energy provider (check your state government for details on any rebates available). On-grid solar panel systems have lower equipment and installation costs, and will save you money through net metering.

An off-grid solar power system uses battery banks to store the electricity you produce. These battery banks store the sun’s energy so you can use electricity at night or on a cloudy day. This system is designed to keep household electricity running for about two or three cloudy days; longer cloudy periods require a backup generator. Off-grid systems are most suited to households that have no access to the utility grid, and are sometimes a cheaper alternative to extending power lines in remote areas.

Hybrid and portable solar power systems are additional options. A hybrid uses two or more renewable energy sources – usually wind and solar, while portable solar systems are used mostly in farming, fishing and camping, and can be set up when there is no access to mains electricity.

What types of solar panels are available?


There are three main types of solar panels that can can generate electricity for your Rockville, VA home: monocrystalline, polycrystalline and hybrid. The basic monocrystalline celled panels are fairly efficient and have outstanding performance in cooler conditions, but are marginally more expensive than polycrystalline, which works better in hotter conditions. Hybrid panels use crystalline cells with a thin layer of film, which attracts more energy. This makes hybrid models the most efficient solar panel installation, but also the most expensive. To talk about which solar panels are best for your home and how much energy they produce, contact a Rockville, VA solar panel company or installer on Houzz.
