Top Tips for Buying Solar Panels
Type of Solar Panel
Nowadays, there are various types of solar panels available on the market. The least expensive option is thin-film PV panels. However, they are also the least efficient. It is advisable to purchase polycrystalline PV panels because of the high efficiency, but they are a bit more expensive. If efficiency is the most important thing you want, then you should consider monocrystalline panels. Unfortunately, they are the most expensive because they have to undergo an expensive production process.
You need to know your energy requirements. When you spend some money at the start, you can get more panel efficiency. No matter the solar technology you use, your solar panel cannot generate a considerable amount of energy in the shade.
Realistic Price Expectations
You should note that the installation and quality equipment are not cheap. If the price you are given is considerably lower as compared to average, you can receive poor quality equipment or installation. Also, low prices may imply that certain services are not part of the complete package. It is a good idea to read the contract and various estimates before committing to the contract agreement.
It does not matter whether the whole packages are great if you need some money. You need to be aware that not all the packages are equal. For instance, a given company can be using quality panels, but compromise on the wiring, mounting system, or inverter. For the solar system to work at an optimal level, all the components ought to be of high quality. You need to compare the different elements carefully.
Ensure you compare different warranties offered by various manufacturers. Ideally, you should expect a warranty of about 25 years. If the company does not provide a warranty of that range, then it means your solar panel may not last that long. For the inverter, the warranty should be in the range of 5 and 15 years. It is a good idea to assess the reputation of the manufacturer. Most solar panel companies have been established for the last few years. If the warranty offered by the company and one with a top brand are similar, you should go for the established brand.
Get Bids from Multiple Companies
You should request quotes from a few manufacturers. This is because the services and prices vary from one manufacturer to another. Avoid making your decision based on the price alone. When you reduce the initial investment, you are likely to end up with the low-quality components.
