What is the negative environmental impact of solar panel manufacturing?
Producing solar panels uses chemicals and produces toxic waste that can be bad for the environment, which is the main drawback of solar panels.
Is it worth installing solar panels on my house?
Solar panels can be a great investment for many homeowners, but honestly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already fairly low, solar panels might not be for you.
What are the different kinds of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof configuration and how much energy generation you want.
