Best brands of solar panels

To find the best brands of solar panels you can use America's most trusted solar panel comparison and reviews website, SolarReviews.

However, reviews of solar panels can be a bit meaningless because most consumer owners have not had any issues and so whilst solar company reviews are very important when choosing solar installers they are of less use when choosing solar panels.

For more information to help you make an informed decision about this topic, I would recommend this article about buying solar panels.

The solar carve out and Delaware SREC's

Delaware has a renewable energy targetthat requires utilities operating in the state to source 25% of their electricity from renewable sources.

The legislature has further mandated that part of this renewable energy must come from solar, this is known as the solar carve out and requires that a certain percentage of that power comes from solar panels.

It starts out small and increases incrementally until it reaches its target of 3.5% by 2025.

The way they enact this program, so that the liable entities (the utilities) do not have to build this solar capacity themselves is to attach a Solar Renewable Energy Credit (SREC) to each MWH of solar electricity generation in the state.

You (or your installer) registers your installation and you can then create and trade these SREC certificates.

You get 1 SREC for each MWh (Megawatt hour) of solar electricity production.

solar carve out have traded in the range of $50 during 2016 but is capped by the value of the alternative compliance payment that utilities must pay if they don't hold enough solar carve out.

For a 5kw system you get approximately 6 solar carve out per year. At a market value at $50 this is an annual return of $250 per year.

Delaware has a slightly clunky method of disposing of SRECS your local Solar Pro will be a good source of info on this.

Use the solar calculator or the compare solar quotes tool to see the current market value of Delaware solar carve out and the effect this has on your solar investment return.



Net Metering in Delaware

Many people don't understand the importance of net metering policy to the residential solar industry.

Solar by its nature generates most power during the middle of the day when most people are at work or school and little power is being used in the home.

Net metering means that for every unit of surplus solar generation generated during the day you effectively get a credit for a kilowatt hour of power purchased from the grid at another time.

Excess generated Kilowatt hours or credits can be rolled over into the next month billing period.

At the end of a 12 month period excess credits can be converted to cash.

This is something that you have to arrange with your utility, your local Solar Pro can help with this.
