"Art performed a quick and professional installation. The solatube installed in the kitchen provides a lot of needed natural light. Also, my existing attic fan had not functioned for several years, and Art suggested the solar powered fan. Art and Steve removed my old fan and installed the new solar fan. Great job all around.

"Harker Heating And Cooling is the best HVAC contractor we have ever worked with in 40 years. Their web site proudly says they are an “honest company with Midwestern values.” That is absolutely true. Their representative provided in-depth advice, answered our questions. and returned our messages. Their techs were knowledgeable, professional, careful, and friendly. They were on time, on call, and on budget. The service they provided for us over the years could not be better. So when the time finally came to replace our old furnace and A/C we selected them. Unfortunately, they encountered many unexpected problems installing our new equipment. Many more than they had anticipated for the job. But their representative pledged to address every one of them no matter how hard it was for them or how much of their time it took. And that is exactly what they did. No quibbling and no questions. They got the job done right. If you want an honest family contractor who stands behind what they do, and lives by those Midwestern values, then this is the company to hire. You will be glad you did.

the old softener was running constantly *went through 100lbs of salt in a day* and we were unable to turn the softener off.  Owner of FP came an hour after returning my call; he turned the malfunctioning softener off and scheduled to install a new softener system the following day.  His son did the installation with his father (owner of business) checking in periodically to offer assistance.)  Very fine people who did a complete job, leaving the work area clean and tidy upon completion of work.  Owner checked back with me a few weeks after installation to ensure all was working well.

Solar Panels FAQs, answered by experts

The average cost to install solar panels is around $27,000, with most homeowners paying between $4,500 and $54,000. These prices don’t consider the federal investment tax credit (ITC), which can reduce costs by up to 30%. The final price depends on several factors, including the size of the system needed to offset your energy consumption, the amount of sunlight your home receives, your geographical location, the type and brand of panels, labor costs, and any add-on products like solar batteries or electric vehicle (EV) chargers. It is recommended to get price quotes from at least three solar companies in your area to find the best deal.

The actual time it takes to construct the solar farm is relatively short, taking between 2 and 4 months on average. That timeline is dependent on site conditions, crew size, and the overall size of the solar farm.

However, the time it takes to get the ball rolling is significantly longer, ranging from 3 to 5 years. With a project of this scale, you’ll need to obtain all of the proper permits and approvals to start breaking ground, and depending on your location, that could be an extended process.

In most cases, solar panels are covered by homeowners insurance because they are considered a permanently attached part of the home, and you may not need additional coverage. However, it is essential to read the fine print of your specific policy to understand the extent of the coverage, as some policies might only cover certain types of damage, such as hail. Always check with your insurance provider before installing solar panels to ensure your policy provides adequate coverage for your investment.

In almost every case, solar panels need to be removed to replace roof shingles. In some cases, such as solar installations where the panels are on raised platforms above the roof surface, installers may be able to install new shingles without removing the solar installation. However, to get a quality roofing installation, panels need to come off. Most roofing contractors won’t remove or reinstall solar panels as part of a roofing project, so you’ll need to contact your solar provider.

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.
