Renewable energy is the future, and solar is leading the way. Solar energy is one of the fastest-growing alternative sources of energy globally. In 2020, solar photovoltaics were responsible for around 3% of the world’s electricity. Currently, leading companies like Apple have transitioned to solar energy, and many more businesses and households are following suit.
Nonetheless, buying a solar panel in Australia is more than picking a unit off the shelf. There is a lot to take into account.
Your energy requirements
Each household or business premises operates on a specific power consumption range. Since the electrical units are often the same, you can reliably estimate the total daily consumption. To calculate your daily power consumption, you only need to take your total annual bill and total kilowatt-hour.
The consumption determines the size and type of solar power system you need. For example, if you use your panels to supplement the council supply, you don’t need a high capacity system. However, if you want to operate your premises off the grid, you will need a high capacity solar power system.
Solar power units have different energy ratings designed to deliver specific power outputs. Therefore you can customize a system to meet your particular needs. If you are not sure how to go about it, consult with an expert.
Solar panels have different efficiency ratings, which demonstrate the energy output for a given panel’s surface area. The more efficient the panel, the less space it takes up. Therefore, residences with limited space and smaller roofs benefit more from efficient solar units.
Currently, most solar panels have an energy efficiency rating of 11-15%. The efficiency depends on the design of the panel and light engineering. There are four main designs in the market:
Monocrystalline silicon panels: This is the most efficient photovoltaic panel. It has high silicon content that enhances the conversion of light energy to electricity. Nonetheless, the high efficiency comes at a cost. The monocrystalline silicon panels are the most expensive photovoltaic panel option.
Polycrystalline silicon panels: If you are looking for an inexpensive solar panel option for a big project, the polycrystalline silicon panel is a great choice. It’s not as efficient as its counterparts but it’s good enough for the job. Another benefit of the panel is the high resistance to heat.
Building-integrated photovoltaic panels: Solar panel installations alter the overall look of a building. However, integrated panels are designed to lie flush on the roof and maintain the original aesthetics of the building.
Thin-film solar cell technology: This is the latest technology in solar panel design. The panels are thin and light. The panel is laminated to existing surfaces like glass windows and metal roofing. The only downsides to the design are the cost and vulnerability to degradation.
The solar energy industry has numerous players. Each manufacturer offers different specifications on their solar panel products. Therefore, it’s essential to get all the details on the different options to make the right choice. Here is what to look out for
Reputation: A highly reputable brand is a safe option. Therefore, go for the big names with a good track record if you want a top-quality product.
Warranty: Most solar panels come with a warranty offer, a manufacturer’s testament that their product is worth buying. The warranty packages also come in handy when your solar power system gets faulty.
The final and most crucial factor to consider when buying a solar panel is your budget. Although solar panels are an excellent investment, they can dig deep into your pockets. Therefore, it’s prudent to get your finances in order before investing.
You can consult different manufacturers to get a full breakdown of the cost of buying and installing solar panels. Nonetheless, no matter your budget, there is something for everyone.
It’s time to go solar. Since everyone is doing it, you should too.
