"Work has been scheduled for early in 2019, but they could not have been more helpful and professional in explaining our options, how our home would get the most out of the panels, and how much we are likely to save. They were explicit about costs and available rebates. We were instructed to apply for a rebate from our local energy supplier and they literally walked us through the time specific rebate procedure. We made some minor changes to their standard contract and they accepted those changes without question. I can only assume their work will be up to these standards when we do the actual installation."

Solar Energy World is a top-rated solar system design and installation company for residential and commercial property owners in Maryland, Virginia, Pennsylvania, New Jersey, Florida and Washington DC. Our mission is to give more people the power to reduce their dependence on dirty energy to foster financial and environmental security for their children and grandchildren because we believe tomorrow matters. We have installed thousands of solar panel systems since our founding in 2009. Solar Power World, the industry’s leading source for solar technology, development and installation news, released their annual Top 500 North American Solar Contractors List in July 2019. Our company made the list again achieving a rank of 85 for total Kilowatts installed in the USA in 2018, moving up from our previous ranking of 117. We also improved our rank of number 24 for total residential kW installed in 2018, now ranking 15 on the list nationwide and have held on to the number one spot for residential installations in Maryland for the third year in a row. In just 10 years we have gone from installing 8-10 solar systems a month to an average of 140 installs a month, making us the fastest-growing, independently-owned Solar Installation company in the region.

"Beware of hiring Solar Energy World I hope this helps someone else avoid the problems that we have been facing with this company. Initially we thought what is the catch, this is too good to be true... well it is. Our panels were incorrectly installed leaving holes in our roofing which led to water pooling in our front porch ceiling and running down the face of our house. We ended up with warped front porch flooring along with mold and water damage in our finished basement. After almost 4 months of us having to follow up weekly and them coming out to correct their improper installation they are now saying that they are not liable for any of the damages to our home. The manager told me that because we moved forward with the mold remediation that they aren't liable. How can a company expect people to live in a home with mold for 4 months while they "review" the situation. The manager then slipped up and admitted that they never reviewed the photos or invoice that I sent over, they just decided in a brief discussion that they werent liable for the damages. When I asked to please speak to the manager that made the decision I was told that he is a difficult man to get a hold of so that won't be possible. I am just shocked and disappointed in this company. We have been so patient and understanding during this whole process to have them treat us like this. Just go elsewhere if you want a company that will do right by their customers because Solar Energy World is not that company."

"Precision air and heat, llc based out of SC and NC installed a condenser unit and evap coil for me over 3 weeks ago. The 2 gentlemen that performed the installation were great and polite. Once done, I informed Precision that the supply temp was fluctuating. They informed me by text and voice that someone would come out to check the refrigerant pressures. No one showed or called. I was also told that I'd receive confirmation that the units would be registered for warranty and an inspection would be scheduled to close the permit. Neither have been done. I called Abdul, the service manager and he made it seem like it was my fallult for not chasing them down enough. I called Asia about all of the above. She said she'd call back and never did. I contacted Roger Costner. He did not apologize or try to make things right. If you've been wronged by them, I'd contact the BBB even though they're not accredited (not surprised). I'd also inform the companies they rep. In my case, it's Tempstar."

Energy Efficiency Auditing questions, answered by experts

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Yes, including optimizing settings and suggesting upgrades if needed.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.
