PV Solar Panels (Modules)

1.What exactly are photovoltaic panels?

Photovoltaic panels are the transformation of solar energy (light) into electrical energy, also called solar power.

2.What do I require to generate solar power?

In order to generate solar power, a solar power system is needed, which can be mounted either on roofs or on the ground.

3.What is solar power system?

A solar power system consists of solar power panels, one or more inverters, as well as a mounting system. Solar irradiation creates a direct current in the solar cells. The direct current is then transmitted to the inverter and is then transformed into grid-compatible alternating current. The produced solar power is fed into the public grid and is compensated by the local grid operator per kilowatt hour (unit).

4.What is a solar power panel?

A module consists of several rows of solar cells that are electrically connected with the help of strip solders. It consists of several layers of material: a special solar glass to provide stability, a translucent intermediate film on which the rows of cells – so-called strings – are placed, another intermediate film and a stable backside film. The films are connected to the glass through lamination, so that the sensitive solar cells are protected against weather conditions.

5.What is the useful life of solar power systems?

Photovoltaic systems of a good quality are hardly susceptible to errors and require little maintenance. Long-term studies show that solar modules can still produce solar power, even after 30 or 40 years. Most PV panels give a performance guaranty of 25 years.

6.Is there a guarantee?

We provide 25 years guarantee and 30 years power warranty

7.Does my roof support the installation of a solar power system?

Basically, solar power systems can be installed on almost all roofs. The best way to decide how they can be installed is through a site visit.

8.Do the PV panels require any maintenance?

The only maintenance required is the cleaning of the modules regularly with water only, especially after one of the ‘dusty’ rainfalls that are quite common in Malta.

9.Should I insure my PV system?

Insurance on your PV system is highly recommended and you need to contact your insurance provider

Micro-Inverter

What is the difference between a micro-inverter and an optimiser?

Microinverters convert DC energy into AC energy right at the panel site. While power optimizers don't convert the electricity on their own; instead, optimizers condition the DC energy and send it to a central inverter that finishes the conversion process.

Heat Pumps

1.What is the difference between a heat pump and a solar water heater?

Solar water heater is installed on a roof and contains copper tubes which collect water, heat it in sunlight, and send it to a water storage tank.

Unlike the large PV solar panel systems, solar thermal panels contain only one panel and can only heat water; they can’t power anything else.

Like your air conditioner and fridge, a hot water heat pump pulls heat out of the surrounding air. It then uses electricity to move that heat into the water tank.

Unlike conventional electric-resistive systems, hot water heat pumps merely move heat from one place (air) to another (water); they use no energy to create new heat.

Due to this efficient process, every unit of energy that goes into a heat pump yields three units of energy.

Thus, while conventional electric systems are lucky to achieve 100% efficiency (you get out as much energy as you put in), the average heat pumps provides 300% efficiency.

You also do not need a roof to install this system

2.Do I need a roof for a Water Heat Pump?

No. You can install in a boxroom in an apartment or a house. A roof is not required for the system.

3.Does the unit consume electricity?

Yes, the compressor unit has a 500W power output. It is much more efficient than a traditional electric water heater.

4.What is the highest temperature that can be reached by the unit?

55 degrees celsius.

5.This system is intended as a back-up system or a complete replacement?

It is designed to provide 100% of the water heating needs of the household.

Energy Storage

1.What is energy storage

A battery storage system stores unutilized energy generated from your solar panel system. In this way, the energy generated during the day is never lost and can be stored in the battery and utilized at night or when the electricity goes out

2.How does it work?

When battery storage is coupled with an inverter, the inverter converts direct current electricity generated by the solar panels into alternating electricity (which is used in most home appliances). The battery then stores the excess electricity generated and stores it. Our batteries:

– Monitor the energy generated by your solar panel system in in real-time
– Monitor the energy stored in the battery.
– Monitor your residential consumption
– Obtain real-time information on what energy you save in the battery and what energy is consumed from the stored energy within the battery.

During the day, solar panels generate electricity, which can first be used to power you home. After which. any excess energy which is not immediately used, is directed to charge the battery. Once the battery is fully charged, any additional surplus may be fed back into the grid or can be used at night or during periods when solar panels aren’t producing enough electricity, ensuring a continuous power supply.
