Choosing quality means choosing durability, efficiency, reliability, sustainability.
A good product comes from a trustworthy brand. The best products are manufactured to last.
Solar is the future, the future of your own system is just as vital as the future of our own planet.
Durability in a solar panel means a solar panel that will not degrade significantly over time. Rather a solar panel that guarantees long-term production.
In warranty terms, a panel with either a 12.5- or 25-year production warranty is a positive endeavour for your home solar. Any reputable solar installer will give a panel that meets this (single) criteria.
Reliability is key in a solar panel; a simple guarantee is given by choosing the right company and taking their advice on a quality panel.
Temperature coefficient and panel efficiency
Two factors to look out for when it comes to solar panels are temperature coefficient and panel efficiency.
The temperature coefficient describes how much power a solar panel loses for each degree the panel rises above its ideal temperature rating.
If the panel has a positive temperature coefficient, it means that as the temperature increases, the panel’s efficiency decreases a little. On the other hand, if the panel has a negative temperature coefficient, it means that as the temperature increases, the panel’s efficiency actually improves a bit.
A temperature coefficient less than -0.42% is considered standard.
A temperature coefficient at or above -0.38% is considered good.
A temperature coefficient less than -0.42% indicates that the panel is able to maintain a relatively stable efficiency even in hotter conditions.
A temperature coefficient at or above -0.38% is considered good because it suggests that as the temperature increases, the panel’s efficiency improves slightly.
Panel efficiency is a measure of how well a solar panel can convert sunlight into electricity. The higher the efficiency, the more electricity the panel can produce from the same amount of sunlight. So, if a panel has high efficiency, it’s great at turning sunlight into power.
A panel efficiency above 20% is acceptable.
A panel efficiency above 22% is excellent.
An efficiency above 20% is considered acceptable because it means the panel is able to convert at least 20% of the sunlight it receives into usable electricity. This is a good level of efficiency and will save money on your electricity bills.
However, an efficiency above 22% is considered excellent because it means the panel is even more efficient at converting sunlight into electricity. Panels with this level of efficiency are highly efficient and can generate more electricity for your home from the same amount of sunlight.
This means extra savings.
An efficiency above 20% is acceptable and will still benefit your home. An efficiency above 22% is considered excellent because it means a higher level of efficiency and a greater level of electricity generation.
A solar inverter takes in direct current (DC) electricity output by solar panels and converts the DC into alternating current (AC) electricity.
The specific mechanics of the inverter can be broken down to its hardware.
A solar inverter is made up of electronic circuits and power semiconductor devices, such as transistors and diodes.
The inverter has a control system that manages the process of converting DC electricity into AC electricity.
The control system constantly monitors the solar panels’ output and adjusts the inverter’s operation accordingly.
This means, for example, if the panels take in less sunlight the inverter lowers its output to match the reduced power being generated.
Many solar inverters have other features, such as maximum power point tracking (MPPT) algorithms. These algorithms adjust voltage and current levels to maximise power output.
What makes a great inverter?
A great inverter is efficient, reliable, and has advanced features like MPPT to optimise power production.
A great inverter is housed in a sturdy and weatherproof enclosure. These enclosures are commonly made of materials like aluminium or stainless steel.
A great inverter protects against all weather conditions. Such as rain, snow, extreme temperatures, and UV radiation.
Extreme weatherproofing may sound like a strong consideration; however, the best inverters cover all considerations.
A great inverter has sealed electronic components. This is to prevent moisture, dust, and other contaminants from entering the inverter.
A great inverter includes features like heat sinks, cooling fans, or liquid cooling systems. Efficient heat management is important for the longevity of the solar inverter.
A great inverter protects from power surges. Lightning and power surges can harm the inverter, so it needs to have protection devices like surge arresters and varistors. These parts redirect extra electricity away from the delicate electronics, keeping the inverter safe from harm.
A great inverter has built-in monitoring capabilities to provide real-time data on its performance. This allows for proactive troubleshooting and maintenance, ensuring that any issues are addressed promptly.
In summary, an efficient and reliable inverter with advanced features like MPPT optimises power production, ensuring that you get the most out of your solar panels. A sturdy and weatherproof enclosure, along with sealed electronic components, protects the inverter from rain, snow, extreme temperatures, UV radiation, moisture, dust, and other contaminants. Efficient heat management through features like heat sinks, cooling fans, or liquid cooling systems contributes to the longevity of the solar inverter. Protection devices like surge arresters and varistors safeguard the inverter against power surges and lightning, redirecting extra electricity away from delicate electronics. Finally, built-in monitoring capabilities provide real-time data on the inverter’s performance, enabling proactive troubleshooting and maintenance.
By investing in a great inverter, you can have peace of mind knowing that your solar system will deliver optimal performance and long-term reliability, while also providing significant savings on your electricity bills.
Solar energy is abundant and clean.
Fossil fuels are finite and contribute to greenhouse gas emissions.
Solar energy comes from sunlight. Harnessing the power of the sun lessens our dependence on non-renewable energy sources. For example, coal, oil, and natural gas.
This not only helps fight climate change but also reduces air pollution and improves overall air quality.
The manufacturing process of great solar brands has become increasingly efficient and environmentally friendly over time.
With energy independence from the grid, great solar products are a must have for the future of our environment, to rely less on classic means of electricity, and rely more on renewable energy.
Many manufacturers go the extra mile, using recycled materials and putting in sustainable manufacturing practices. This in turn reduces the environmental impact of quality products.
In summary, great solar products are better for the environment. They rely on renewable energy, reduce greenhouse gas emissions, improve air quality, have a long lifespan, offer energy independence, and are produced using environmentally friendly practices.
