Solar energy is becoming the next big thing when it comes to renewable and reliable energy. This resource is preferred over others because it’s plentiful, green, clean and available in any part of the globe. Its uptake has however been low due to the high initial cost of installation. However, this is gradually changing as solar panels also known as photo-voltaic (PV) cells become more affordable, efficient and durable.
Other than the cost of installation, the cost of maintaining the same is relatively low considering you don’t incur any monthly power bills. We have taken a look at the top 10 best solar panels in 2020. Nonetheless, it’s also beneficial to know what makes a good solar panel.
How to Choose a Solar Panel
The following aspects are critical when choosing or comparing solar panels:
- Power: This is rated in watts and determines how many appliances can be connected to the solar system. The higher it is the more powerful the unit.
- Warranty: Solar panels have greatly improved and become more robust and reliable. Top brands are backed by a warranty of as many as 25 years.
- Area of Use: A panel that will be mounted on an RV, caravan or small apartment will be much smaller than the one(s) to run a large institution. Also, remote locations that fully rely on solar energy will need bigger and more powerful units compared to a home that only uses the solar system as a backup.
- Budget: High capacity or top-end panels cost more than low capacity or low-end types. You can start with a small unit and continue to add on additional pieces of overtime. 20-60 watts panels are fit for caravans and RVs while homes and offices do well with a panel that is at least 100 watts.
- Mode of installation: Rigid panels are meant to be fixed permanently while flexible or rollable solar mats can easily be uninstalled or carried.
Other important considerations include solar efficiency, durability, brand, dimensions and customer support.
