With the Earth’s energy reserves depleting quickly, renewable energy is the need of the hour. Many environmentally conscious homeowners are now opting for renewable energy sources like solar and wind energy, which harness energy from natural sources. Solar power, which relies on sunlight to harness energy, is emerging as a popular alternative fuel source for several homes. But before installing a residential solar power system, one should consider a few aspects.
Tips to install solar power systems at home
1. Evaluate personal energy requirements
To choose the right solar panel, one must consider how much energy the household consumes monthly. This estimate can be made based on the type of appliances one owns, how frequently each is utilized, the number of members in the household, etc. Based on this estimate, one can predict how much of the utilized energy can be offset with solar power. With this information, one can decide the type of solar panel best suited for one’s household.
2. Research the different types of solar panels available
Solar panels are available in three types: polycrystalline, mono PERC, and half-cut. The type of solar power system ideal for a home depends on one’s energy usage and the household’s budget limit. In addition to considering these factors, one should thoroughly research each type of solar panel, its distinct features, pros and cons, and the average installation cost.
- Polycrystalline solar panels: These panels are the most affordable and are suitable for areas with high temperatures. They are also quite space-efficient, which makes them ideal for smaller homes. That said, they are less efficient than the other types of solar panels. Also, their raw materials come from different sources, so the color of these panels isn’t uniform, making them less aesthetic.
- Mono PERC solar panels: These are generally more efficient than polycrystalline panels and can function well in narrow roof spaces. They can also function in different light conditions and temperatures and are durable. But the downside is that they are more expensive than polycrystalline panels. Also, since they are made of a single silicon piece, they may require additional panels and space for larger installations.
- Half-cut solar panels: Based on relatively new technology, half-cut solar panels are extremely efficient and offer higher wattage than the other types of solar panels. But these are the most expensive solar power systems, and internal malfunction can occur after the cutting process.
3. Consider the size of one’s home
The size of one’s home is important in deciding the type of solar panel to install. If a home has less space, it’s a good idea to opt for smaller, more compact solar power systems or a combination of traditional and solar power. But a large-scale installation would be ideal for homes with more space. So, one should measure the available space before installing a residential solar energy system.
4. Use the divide-by-four rule
An effective way to calculate the number of solar panels one needs to install is to divide one’s highest kilowatt usage by four. This way, a household utilizes only the energy required and ensures that the solar panels don’t take up extra space. It also reduces the total cost of installation.
5. Consider the location
The location of the home should also help one decide the type of solar panel to buy. So, those living in tropical areas with high temperatures should go for panels with high-temperature ratings. In contrast, those living in cooler climates should look for panels with low-temperature ratings.
6. Ensure that the panel is certified
When buying a residential solar power system, one should look for panels certified by authorized entities, such as the ISO or ALMM. Certified solar panels are approved for use in residential areas.
7. Compare the features and prices of solar panels by different brands
The more solar panel options one considers, the more one has an idea of their standard features and prices. It’s important to research the reputation of brands and specific products and check whether the features justify the cost of the panel. It’s best to opt for a solar power panel that perfectly balances one’s requirements and the features offered within one’s budget limit.
8. Seek professional assistance
While choosing a solar power system is no rocket science, it can be overwhelming for first-time buyers. Hiring a professional solar power expert can help one make the right decision. These professionals are adept at understanding one’s requirements and budget limits and suggesting the ideal system. They also help with end-to-end installation and maintenance of the panels.
