Factors to Consider When Buying Grape Solar Panel 

Price

One of the most important aspects of people switching to solar panels is the price. It is a valid concern because price isn't as tangible as when buying a generator. Are you going to save money in the long run if you buy that particular kit? The following things could answer this question:

  • Components included - The Grape solar panel kits are differentiated by the type and number of components displayed. Surely, the type of components installed also contribute to the tag price.
  • Professional installation costs - Lamentably, some of the states forbid do-it-yourself solar panel installations. You have to pay for properly installing solar panels otherwise you cant do it on your own.
  • Tax credits and other types of monetary incentives - There is a solar federal tax credit of 30% (if you install the equipment from 2016 to 2019), even up to 26% for 2020. 

Performance

  • Solar panel efficiency - What amount of usable electricity can your solar panel convert from sunlight? Solar panel efficiency is the answer and the higher the number, the better. As a rule, solar panels operate with the efficiency between 14% and 18%, although the best ones may reach 24 %.
  • Temperature coefficient - This coefficient shows how solar panels work at non-favorable temperatures. Try to find solar panels with lower temperature coefficient (about -0. 25 to 0. Generally Grape Solar modules belong to the band in the middle of temperature coefficients. For instance, if your kit says it is -0. 0.25 temperature coefficient, which is the symbol of many solar panels. They will produce . 25% for every 1°C rise in temperature.

Warranty

The majority of the solar panel producers, such as Grape Solar, are generally reckoned to provide a 10 year warranty against defects on the parts. Some kits have different warranty policies depending on the brand, so please inquire details first before purchasing. This is a very important consideration since nobody would like to be left with a defective solar panel after only 5 years of using it when the panel has not yet delivered its complete worth.

Wrap Up: Which is the Best Grape Solar Panel for My Home?

The key factor here is choosing a solar panel kit that can meet your necessary needs, particularly, if you intend to use them in places like your cabin that are far from town.

Also keep in mind that these three Grape Solar reviews gives you the idea how other people used them regarding their installations. The decision of using solar panel kits for your home power needs should take into account the criteria mentioned above.

Furthermore, you might have an idea of other expenses apart from the cost of the solar panel kits. These types of Grape Solar Kits listed above don’t include batteries yet, so you need to add another 200 dollars if you want to start fresh.

The best thing about all three - the Grape Solar GS-100-KIT Solar Panel Kit, Grape Solar GS-200-KIT Solar Panel Kit and Grape Solar GS-400-KIT Solar Panel Kit is that they are all expandable, so you can begin your solar project now and add more panels in the future.
