As energy becomes more and more expensive, solar panels become more and more popular. Think about it: why don't you want to use free renewable energy from the sun? However, installing solar panels has never been as easy or straightforward as people think. You need to consider the initial cost and choose the best type of solar panels for your house. Then there is the whole process of installing them and connecting them.

However, this should not stop you from investing in solar panels. After all, once you install them, they will save you bills, let alone add value to your house. That's why we've summarized this guide to the basics you should know before buying solar panels.

4 things to know before buy solar panels.
1. Is your roof ready to install solar panels?
If your roof is old or damaged, you may not be ready to bear the weight of solar panels. You should have it checked by a professional to see if its structure is reasonable. It is best to make any necessary repairs before ordering the panel. At the very least, your shingles should be relatively new; otherwise, you will need to remove the entire grid to repair it in the future.

If your roof cannot bear the weight and you are not prepared to pay for a replacement, you can also place solar panels in the backyard. Just make sure you point them in the best direction of the sun.

2. What types of solar panels are available?
There are three main types of solar panels to choose from; monocrystalline, polycrystalline, and thin film. Monocrystalline is the most common option you will see on homes. This is considered to be the most efficient of all solar panels, but is therefore expensive.

In contrast, polycrystalline panels are slightly less efficient, but they don't cost as much. On the other hand, thin-film panels have a more elaborate design, which makes them more flexible and portable. However, these are not as efficient as monocrystalline. The best option for you will depend on your home and budget.

Then there is the question of solar panels versus solar tiles. In comparison, solar panels are more traditional and less costly. Solar tiles are newer and instead of sitting on the roof, they are designed to look like your shingles, so they are more aesthetically pleasing. However, solar tiles are much more expensive than solar panels.

3. What is the price of solar panels?
Before you buy, make sure you fully understand the cost of installing solar panels. On average, it is expected to spend at least $15000 to $20000 to buy and install solar panels. You may need to hire professionals to install them, and you need to consider in advance any repairs that may be needed on the roof.

Be prepared that although you will save money on the bill, it will take a long time to recover the initial cost. Many solar panel installers provide a calculator to see how much you can save each month if you have solar panels.

4. Is it better to buy or rent solar panels?
One of the biggest questions you will face is whether you should buy or rent solar panels. If you rent a panel, you don't have to pay a lot of upfront costs, usually about $10000 or more. However, if you select this option, you will not officially own the panel device owned by a third party. In addition, it will not add value to your property because it is not a permanent asset and you will not be able to apply for a tax credit.

However, the lease is not a complete loss. Over time, it can still save your utilities, and you won't have initial upfront costs.
