4 Mistakes Homeowners Make When Going Solar

4 Mistakes Homeowners Make When Going Solar

By Solar Panel Installation Process No Comments

 

Buying a solar system for your home can be a confusing process. At Solar.com we’re committed to helping homeowners sort through it all and go solar with confidence. Here are some common mistakes homeowners make while going solar.

1. They miss out on rebates

Currently, there is a 30% federal investment tax credit for solar which is installed prior to December 31, 2016. States, cities, counties, and utilities all over the country offer various rebates and tax credits in addition to the federal ITC. Be sure to research all of the subsidies in your area before purchasing your system. Remember, if you lease your system or sign a power purchase agreement (PPA), you do not own your system and so the tax credit and rebates go to the solar company, not you. This means you may lose out on more than half the value you would have realized if you had purchased the system. If you can take advantage of these incentives, purchase the system with cash or finance it with one of the many solar financing options in the market.

2. They don’t shop around

Solar is a growing market and consumer knowledge is low. Predatory solar companies and salesmen take advantage of this lack of knowledge by overcharging homeowners and using sales tactics to pressure homeowners into signing a contract which may not be in their best interest. Recently, we had a customer show us a quote they received for $7.15/watt. Read about it here. On average, we find quotes for less than half that price. At Solar.com, we eliminate the salesmen and collect bids from dozens of top solar companies while keeping your information completely confidential. This means you are not harassed by numerous installers calling you and knocking on your door. No obligation, completely hassle free.

3. They don’t get the right size system

Our customers often show us competing bids they have received, and we are surprised to find how often installers oversize the solar systems they design. Installers have a financial motivation to sell larger systems, but it may not make sense for the homeowner. Installers will put panels in sub-optimal spaces to increase the size, but the savings won’t be realized by the homeowner. If a system is oversized, some utilities will not allow it to be turned on. Each utility’s electricity pricing tiers dictate the ideal amount of electricity your solar system should offset – it’s almost always less than 100%.

4. They don’t ask enough questions

Solar PV systems require a lot of components. With panels, inverters, panel boxes and more, there’s a lot to consider. Workmanship warranties from solar companies range from 1-25 years and each component has its own manufacturer’s warranty with similar ranges. Warranties are one of the most important factors in a solar system and are far too often overlooked. If your system breaks and there is no warranty, you’re out of luck. Be sure to ask your solar company for specifics on their warranties. Solar.com considers both component and workmanship warranties as well as panel bankability (read more here) in our bid assessment algorithm in order to make sure our customers get deals that won’t come back to bite them.

CONCLUSION:

So, you could do all this and hope you find a great deal, or you could use Solar.com and have them do the work for you at no cost. Check out the Bid Generator to get started!

 

Does Solar Panel Efficiency Really Matter?

By Solar Panel Efficiency - Pick the Most Efficient Solar Panels No Comments

Installers who sell high-efficiency panels love to flaunt that point when selling their system. But in most cases, panel efficiency doesn’t count for much, except higher prices. Having the highest efficiency panels on the market does not mean your system is producing the most. The watts of a system will be the single largest determinant of system production, not efficiency.

 The straightforward definition of panel efficiency is the percentage of solar energy that is converted into electrical energy. To give an example of this, the average dimensions of a residential solar panel is 3.5ft. X 5ft.; this panel may produce anywhere from 250 watts to 345 watts. The difference in watts is determined by the efficiency of the panel. Today, residential panel efficiency tops out at about 22% (345-watt panel) and it bottoms out around 15% (250-watt panel). Approximately 95% of the panels on the market will fall in this range.

Reasons to get high-efficiency panels: If you have limited roof-space or limited optimal roof-space, and you cannot fit as many watts on your roof as you would like, then it may make sense to pay more for the higher-efficiency panels. Other than that, you’re just paying more for the sake of paying more.

Reasons to get lower-efficiency panels: They will save you a whole lot more than paying the high price of the latest technology. If you are buying a new pair of skis or a new car, you get technological improvements you can enjoy. With solar panels, they all produce the same thing – kilowatt-hours of electricity (kWh). Lower-efficiency panels will produce the same kWhs as high-efficiency panels, but they’ll take up a bit more space to do it. Check this video to find out what is a kilowatt hour.

Exceptions: There are all sorts of other considerations when choosing panels. Sunpower’s extremely high-efficient panels offer the industry-leading warranty, SolarWorld panels boast that they’re American Made, and LG has some serious brand recognition. All those factors may play into your decision of what panels you want, but don’t let the efficiency play a major role if you have the roof-space – otherwise, you’re just giving money away.
