Frequently Asked Questions

1. When the energy price increases, the worth of your KWh production also rises. Your buyback sell rate is also a factor as the more you get from your excess solar energy production, the more your savings will be.


2. System Production. The more KWh your system produces, the greater savings you’ll receive.


3. Self-consumption. The solar energy produced can be used for personal consumption or sell the excess energy to the energy retailer or back to the grid. Savings coming from your personal consumption are usually higher than from the energy sold.

Solar panels may look the same, but they have great differences when it comes to features and quality. You may hear the term ‘panel efficiency’ when choosing solar panels. But what is it anyway?

Panel efficiency is the amount of sunlight your panel can convert to usable electricity. When choosing the right solar panel, it is necessary to identify which will produce more energy considering the amount of space and the access to sunlight. Factors that may affect panel efficiency are discussed below:

1. Reflectance. Defined as the amount of sunlight reflected back instead of being absorbed and converted to energy for consumption. The less the reflection, the better. Anti-reflective coatings can be used today to reduce this.
2. Thermodynamic efficiency. ii.Photons and solar cells can generate electricity only up to 86 percent. After reaching that point, thermal energy is being produced. A way to improve thermodynamic efficiency is to establish tandem solar cells which divide the solar spectrum into smaller areas, increasing the efficiency limit for each cell.

The main difference between monocrystalline and polycrystalline is the type of silicon they use. Monocrystalline panels contain solar cells made up of a single crystal of silicon while polycrystalline solar panels have cells made from a number of silicon fragments melted together.

Monocrystalline panels are considered more expensive yet provide higher efficiency and glossy appearance. In making this type of panel, silicon is formed into bars and cut into small slices and since the cell is composed of a single silicon crystal, the electrons that generate the flow of electricity have more space to move, making it more efficient than polycrystalline.

Instead of using a single crystal of silicon, polycrystalline panels are made up of melted fragments of silicon to form the slices for the panel. Multiple crystals in each cell provide less freedom for the electrons to move.

When sunlight hits a solar panel, the panel begins producing direct current electricity. The direct current electricity is being absorbed by a solar inverter which will then convert it into alternating current electricity, this is used to power households and commercial establishments.

Adding batteries in your solar panel system is possible. This is called AC-coupled storage where a battery system and a battery inverter are being added to an existing solar power system. Any excess electricity will be stored in your system’s battery pack.

Solar panel systems work only with the visibility of sunlight and there is not enough light produced at night to sustain the solar system’s activity.

Your solar panel system will switch off within a few milliseconds during power outage, a safety feature of your solar system structured to protect those who may be working on the blackout grid system. If it continues to run during a power outage, those working on the grid will be at risk of electrocution. If you want to keep on having available power during blackouts, then you would need to consider installing a battery pack.

Yes. The solar systems we sell are covered by a performance warranty. Additionally, manufacturing warranties can cover your entire solar system for up to 10 years. Warranty specifications may differ from one product to another.

Also, your warranty may cover most of the mechanical defects your system may encounter during the warranty period as long as they are accounted as manufacturing fault.

Several aspects shall be evaluated to identify if your business is suitable to use a solar panel system. Roof orientation, available space, shadows and current electricity consumption are some of the factors to be keen to. Good solar sites are those with north-facing roofs and have no shade.
