Here's How It Works


Generally, the solar energy is supplied directly to your home or workplace as needed during the day, and unused power is sold into the grid, earning you a low credit on your power bill with your electricity retailer. With SESS, your solar panels will also directly power your appliances or equipment during the day, but the extra power does not go into the grid and gets stored in your battery, which is availa ble at night or at any time you need it. While, you can possibly still earn credits on your power bills because when your battery is full, your solar system will send power back into the grid automatically.

The main difference between Off Grid SESS and On Grid SESS is whether it can sell solar powers into the local utility grid. If not, it's cheap and enough to choose Off Grid SESS. Off Grid SESS emphasizes the efficient and full utliliation and management of the clean energies solar systems makes, Off Grid SESS can also work together with GENSET, and save much fuels. With SESS, your off grid SESS Can directly power your electric appliances in sunny days, and store the extra electricity in your battery pack, which is available at night or at any time you need it.

Frequently Asked Questions

In the UK, the best direction for a roof to face is south, provided it isn’t covered by shade. Solar panels will work on an east or west-facing roof with a slope, or pitch, of between 15 and 45 degrees, generating enough energy for home use. Panels facing to the north will not generate sufficient energy.
Generally, the smallest solar panel systems are a minimum of four panels, as that’s how many are needed to enable the system’s inverter to function. Mid-terrace and end-of-terrace addresses are generally suitable for four panels or more to be installed, depending on whether the roof is clear of obstructions like Velux windows, chimneys, soil-vent pipes or other features that reduce the space needed for the panels.
Daylight is all that is required for solar panels to produce energy to be used in the home. Even when it’s cloudy, foggy, overcast and in winter, solar panels capture whatever sunlight is available.
In most cases, even for larger jobs that include the installation of a home energy storage battery, the installation takes no longer than a day to complete. If an unforeseen disruption were to take place causing a delay in the installation, it still shouldn’t take longer than two days. Scaffolding is typically erected 24-72 hours before the arrival of the installation team.
Solar PV systems have no moving parts other than the inverter, and as such have very long life spans. The inverter should last for more than 10 years, and may cost £1,000 or less to replace, depending on the model required to support the panels installed. An extended, 10-year warranty is often offered by the installer prior to fitting, or can be directly arranged with the inverter manufacturer upon completion of the installation if required. This extends the warranty from the standard 5 years up to 10 years in total. Panels should last more than 25 years with performance guarantees in place to ensure a satisfactory level of performance for at least the first 20 years in most cases.
If you experience a power cut that directly affects your home, your inverter will automatically switch off, preventing energy from entering the property. This is a safety feature to protect workers who may be repairing the grid. However, there are back-up systems such as home storage batteries that can enable you to use stored energy in case of a power cut.
As solar PV panels produce electricity solely in daylight hours, this doesn’t generate enough energy to power the home for a 24-hour period. To power the house at night without the need to draw from the national grid, you would need alternative energy sources such as a home storage battery in combination with a solar PV system. Most solar PV installations for domestic properties in the UK, however, are not generally configured to enable complete off-grid functionality. This is mainly because AC current is drawn from the grid to help maintain power to the solar PV system’s inverter. During the evening, most homes will require a small amount of AC power from the grid in order to function correctly.
Once the solar panels have produced energy by converting sunlight in the form of a direct current (DC), this needs to be converted into an alternating current (AC) before it can be safely used in the home. The inverter’s AC cables will then carry that energy to your mains distribution board, after which it can be used to power your home.
Energy storage - in the form of a home battery - improves how energy can be stored, delivered and consumed. This can be useful during power cuts, or working with a solar PV system to store the energy generated during the day for use at night. In most cases, the presence of a home battery delivers cleaner and more cost-effective ways for energy to be drawn, stored and used when compared to traditional energy use.
Solar panels are generally self-cleaning if positioned at an angle of 15 degrees or greater. We advise that you check annually to ensure there’s not buildup of residue that needs to be removed. Most window-cleaning companies offer services that can clean your panels if necessary.
