9 Things to Consider to Buy Best Solar Systems for Home

Switching over to this renewable technology may intimidate you in the beginning. It requires planning to know where to begin. You may wonder what will be the cost, and how to select the right panels for your home type. Therefore, here know these things before getting into it;

  • Power Consumption
  • Type of Solar Panels
  • Performance/Quality
  • How Many Panels Do You Need?
  • Roof Compatibility
  • Mounting
  • Cost
  • Durability
  • Warranty

1.      Power Consumption

To calculate the consumed power at your house, you need to look at the electricity bill. It will give you the electricity usage under the “Electricity Used” or something similar. If you don’t find such a value on the bill, go for the meter reading and subtract the previous one from the most recent reading. You should have your power consumption ready.

Now you want hourly or daily consumption as well. If your electricity bill doesn’t show such a value, just divide the monthly reading by 30 and you will have your daily consumed power.

You need these values to decide how many panels you need. Or you can benefit from the installation services by the service provider company and they will guide you for everything after these main calculations.

2.      Type of Solar Panels

There are different variations based on the type of cell used in a solar panel available in the market. You can choose any type which suits your requirements. Each type has its own pros and cons. Here, we have described them;

The mono-crystalline cells are the oldest and offer a higher conductivity rate. These are in high demand, however, they are costlier. Alternatively, you can use polycrystalline cells. They have less conductivity rate as compared to the mono-crystalline cells but they are cost-effective. The third type, thin films, is the latest technology. The output rate is less than the other two mentioned types. But these are available at low prices so they can give you the benefit of fewer electricity requirements.

3.      Performance/Quality

Using the higher quality panels isn’t the point here. You can use the most efficient one but what if it doesn’t give you the required output? So, the performance depends on many factors. Such as, your choice should produce enough electricity, and batteries should charge faster.

According to research, the average efficiency of solar panels is around 15-22%. So, if your chosen type is producing electricity within this range no matter the material used, it will benefit you in your lifetime.

4.      How Many Panels Do You Need?

Do you have an apartment of 3-bedrooms or a house of 2000 square feet? You may be wondering how many solar panels you should use for your place. All the confusion will be gone, once you know;

  • Average energy used
  • Current used
  • Sunlight
  • Type of the panel
  • The physical size of a panel

You need to check if there is enough space on your rooftop for the selected amount of panels or not. If you are working with an expert, then you can calculate these values on your own. But if you’re new to this technology, you can contact your service provider as well.

5.       Roof Compatibility

You need to analyze which area of the rooftop is getting the most sun exposure. The more sunlight a solar panel gets, the more electricity it will produce. Do not let any obstacle come in the way such as trees, buildings, or other structures. As they will block the sunlight resulting in minimizing the output as well. For such instances, where you are worried about which is the best solar brand for your home or business, Maxpower provides the most long-lasting solar panels globally.

6.      Mounting

If you live in a windy area or a region where the weather doesn’t stand a chance, you need to keep an eye on the mounting of the panels. Loose connections can cause disruption in the energy flow. Moreover, loose brackets can cause the panels to fly away in severe winds as well.

If your rooftop is too risky or not feasible for the solar panel installation, then you can use your backyards for its installation as well. Also, the compatibility of more sunlight exposure must be ensured before doing this.

7.      Cost

Adopting this renewable energy source will give you a certain lifetime benefit. Taking a note of the solar panel system’s cost is necessary, doing prep before going to market is necessary. Like, one should evaluate how much energy is needed to run the space, thus, this will help the owner to get an idea of how many panels are needed. Mainly, the factors adjusting the prices of the solar system are;

  • The number of panels
  • The wattage of each plate
  • Inverter efficiency
  • Number of batteries
  • Battery’s Storage Capacities

There are other expenditures that you need to consider as well–such as the hassle in the installation of arrays, tieing the system to grid, etc. You will have to make the payment upfront or you can purchase the installment packages as well.

8.      Durability

Since the open climate will affect the panels, you should consider the durability factor of the solar panel. Panels should be strong enough that they can undergo severe weather easily. Or it will be a huge hit on your savings if they are broken or damaged. So long-term durability must be negotiated with the service provider, in the beginning, to avoid any mishaps in the future.

9.      Warranty

Warranty is your right as a customer. If you are making such a huge investment, it is best to discuss the attractive warranty period with the service provider/company. It will help you to maximize your investment by covering the expenses in case of any damage to the solar panel.

Now you can compare different companies’ solar panels based on the discussed tools. Going all green with renewable energy requires a big step. You’re all set to take it.

How Do Solar Panels Work?

The sunlight is used as a source to convert its energy to power the grid. Solar panels use PV or photovoltaic cells to work. This PV cell absorbs the sunlight and converts it into an electric charge. Part of the PV cell converts the DC into AC so it can be used in homes. The areas/regions where there are low chances to get sunlight, PV cells can also store energy for later use.
