Factors Affecting The Cost Of Solar Panels
Investing in a solar system is beneficial since solar energy can be more affordable than using electricity and fossil fuels. Additionally, solar power is renewable and doesn't pollute the environment. However, you need to know how much your preferred solar panels cost to see whether they fit your budget. But, the costs differ due to various factors. Here are the factors impacting solar panel installation.
Roof Size and Orientation
The amount of space on your roof determines the size of the solar system that can fit on the roof. For instance, a small roof space can accommodate a small solar panel. Small solar panels usually cost less than large panels, but they harness less power energy. While large panels may cost more, they can harness more energy to satisfy your household power needs.
Additionally, shallow or steep roofs aren't efficient for exposing the solar panels to the sun for extended periods. This results in reduced output which increases the costs of running the solar system. In contrast, a roof with a good pitch and orientation ensures optimal performance of solar systems, reducing inefficiencies. That lowers the overall running costs of the system.
Household Power Demand
A home with many electrical systems such as water heaters, cookers, and AC systems has a higher power consumption than a home with gas appliances. You can estimate your home's power demand by studying your monthly power bills. Once you establish your home's power needs, you can select the ideal solar system.
However, the higher the power demand, the larger the capacity of your solar system. Note that high-capacity solar systems usually cost more than low capacity systems. If your budget is small, you can purchase a low-capacity solar system to offset some electrical needs. For instance, you can use solar power for heating only and use electricity on other home systems.
Installation Type
There are two main solar panel mounting options:
- Roof mounting: Solar professionals install roof-mounted solar systems on roof brackets. The roof installation is less costly and saves on space. However, accessing the roof may be difficult. That's why you need professionals to do the installation as they have the right expertise and equipment to navigate various roof systems.
- Ground Mounting. Solar panels install the solar mounting on the ground. Ground preparation work is required, which increases the installation costs. Hence, you need to choose affordable solar services. Additionally, ground solar systems are easily accessible, making maintenance easy.
These two mounting systems are efficient and you should choose the option that works for you.
The common factors affecting the cost of your solar system include the roof orientation, installation type, and household power demand. Consider these factors to estimate the cost of your solar panels accurately.
