Is 4.04 kWp enough to power a house in Malta?2023-03-07T19:27:23+01:00

Yes, 4.04 kWp is generally enough to offset average power consumption of a typical family household in Malta. However, energy consumption is highly specific to each household, and it is often the case that in order to completely offset energy consumption, a larger, or smaller PV system with or without battery storage may be required. You can always refer to us for free consultation regarding your energy needs and a perfect solar system to address your specific requirements!

One should also consider that peak energy consumption tends to occur in the evenings, when solar power may not be sufficient, whilst peak solar generation happens around mid-day, when household consumption may not be too high. Therefore consumption and energy generation do not coincide in time, which implies that some of the excess solar energy ends up being exported to the grid, whilst at other times, household would still need to import electricity. In order to maximise as much as possible the use of own produced solar energy, one would need to consider a battery energy storage system, which would store excess solar energy generated during the day, and release this energy on demand in the evening, or at times when solar power may not be sufficient.

Is buying solar panels worth it in Malta?2023-03-07T15:58:04+01:00

Yes, buying solar panels in Malta is definitely worth it. Malta has some of the best conditions for solar power in Europe, with an average of around 3,200 hours of sunshine every year and a high level of solar radiation. Additionally, the cost of electricity in Malta is moderate, making solar a more attractive option than other forms of energy.

Finally, the Maltese government offers generous incentives to homeowners who install solar panels, including grants, tax credits, and net-metering. All of these factors make investing in solar a great option for homeowners in Malta.

The more power a solar panel has – the better?2023-05-23T08:51:51+01:00

This is one of the most common misconceptions about PV, and one that has often misguided many consumers into unnecessarily spending more money on higher powered panels they do not really need.

Indeed a PV system consisting of higher powered panels does NOT necessarily provide an overall better value compared with a system consisting of less powerful panels. More often than not, the opposite is true!

Firstly, it is worth noting that under current regulations, the maximum permissible power output of a PV system allowed on a single phase is limited to 3.68 kW AC. This means that no matter how many solar panels one would wish to install on single phase, the combined OUTPUT power of the inverter SHALL NOT exceed 3.68 kW.

Moreover, another regulation states that the maximum size of a PV system connected to an inverter should not be more than 20% larger than inverter’s rated AC output. Therefore if a single phase inverter’s power is limited to 3.68 kW (AC), the maximum DC power of solar panels cannot exceed 4.416 kWp (DC).

For the sake of an example, this maximum power can be approached by having either 11  solar panels rated at 400Wp (DC) each (4.4 kWp), or 8 panels 505Wp each (4.04 kWp).

Although higher-powered solar panels tend to take up less space, they also tend to be more expensive than solar panels with lower power rating.

At the end, whether one uses 400Wp panels or 505Wp panels, the power output of the equivalent PV system would still be the same!

What are the best solar panels in Malta?2023-05-23T08:33:58+01:00

Malta’s climatic conditions including exposure to high temperatures, wind and high levels of humidity, as well as close proximity to the sea present a challenge to quality and reliability of solar PV systems. Under such demanding conditions, only the top quality solar panels with the highest efficiency, low temperature coefficient, high degree of environmental protection for electronic components, and robust frames, should be used.

What are the uses for PV panels in Malta?2023-05-23T08:22:18+01:00

Solar Energy for Homes

PV panels in Malta are particularly suited to residential rooftop installation for energy self-sufficiency. Solar energy generated by rooftop PV systems allows homeowners to generate free electricity from the sun during daylight hours. This can lead to savings on electricity bills as well as reduced reliance on the grid. Households can also benefit from attractive government incentives that range from direct grants on the purchase of home PV system and battery energy storage, to feed-in tariffs for solar energy sold to the grid.

Solar Energy for Businesses

Malta’s abundant sunshine provides ample opportunities for commercial businesses to benefit from solar power. Businesses can install larger solar systems on the roof, replacing or reducing their reliance on grid electricity and mitigating their energy bills, and benefiting from attractive feed-in tariffs.

Solar PV and Battery Energy Storage

With the increasing availability of battery storage technology, rooftop PV systems can act as independent micro-grids. This allows for storage of the electricity generated during daylight hours to be used at night when energy from the grid is typically more expensive. This is referred to as ‘demand response’ and allows homeowners and businesses to save money while reducing their reliance on the grid.

What can I do if I cannot afford an initial investment?2023-02-08T19:26:07+01:00

In reality, some PV systems offered by Virtue Solaris require NO upfront investment at all. For example, it may be possible to acquire a quality PV system WITHOUT any deposit, and with monthly repayments starting from as low as €49.

What’s more, the value of monthly repayments would, in most cases, be equal or less than the value of savings in electricity bills. Thus under some conditions, it is possible to install a high quality PV system virtually for free!

What can ruin solar panels?2023-03-04T13:49:00+01:00

Excessive heat, strong winds, hail, snow, dust, debris, and bird droppings can all damage and degrade solar panels, reducing their efficiency and lifespan. Extreme weather conditions such as hurricanes, tornadoes, flooding, or lightning strikes can also cause irreparable damage to solar panels.

What do solar panels do when a battery storage system is full?2023-03-04T13:49:34+01:00

When the battery storage system is full, solar panels will divert any excess energy generated back to the utility grid. This process is called “net metering” and it ensures that homeowners are not wasting the energy their panels are producing.

What if I don’t have much space for solar panels?2023-05-23T08:56:28+01:00

If you own a property with a roof, no matter how small, PV panels are simply a must.

A typical PV panel takes up only about 1.5 – 2.3 square metres of space, and a decent domestic PV system can take up as little as 20 square meters of space.

That’s typically less than the size of an average washroom, a yard, or roof terrace.

Virtue Solaris offers its customers tail made solutions for EVERY roof. In some cases, PV panels can be elevated on a custom-made structure, which would allow continuous use of the roof for any activity, be it roof garden, a BBQ space or simply the place to hang one’s laundry!

What is the average cost of home solar system in Malta?2023-05-23T08:38:10+01:00

The average cost of a typical single phase PV system in Malta is around €3,220, after government grant, and can vary between about €800 to over €1,000 per kWp of solar panels installed, depending on actual set up, mounting arrangements, length and passage of cables, and choice of equipment.

What is the cost of 20 solar panels in Malta?2023-05-23T08:43:07+01:00

The cost of 20 solar panels in Malta depends on several factors, including the type of solar panel and the brand, as well as the size and power output of the panels. Generally, prices for solar panels in Malta range from about €800 to over €1,000 per kW of installed capacity, with 20 panels providing between 8 and 10 kW of installed capacity. Get our latest offer for a 20 solar panels system here!

What should you avoid with solar panels?2023-05-23T08:26:36+01:00

It is important to avoid obstructing the panels from direct sunlight, as this will reduce their efficiency. Additionally, solar panels should not be exposed to heavy dust, dirt, or other particles, as this could also reduce their effectiveness.

Why get a battery storage system?2023-02-18T21:15:17+01:00

Virtue Solaris offers its clients a unique battery storage solution based on high voltage lithium ion batteries produced by renown electronics manufacturer Huawei.

These batteries can accumulate surplus energy produced by a PV system during the day, and release this stored electricity for consumption during the night, or at any time when PV energy is not available. Over time, this solution invariably leads to considerable financial savings, since the household becomes virtually self-sufficient when it comes to energy needs.

Why should I even bother installing solar panels?2023-02-08T19:29:19+01:00

On average, a typical Maltese household spends around €1,200 in energy bills each year. That’s a staggering €24,000 over a 20 year period!

Think of what you can do with an extra €24,000 in your pocket. Perhaps an extra holiday break each year? A gym membership for all the family all year around? Replace that old car with a new, fuel-efficient one, or perhaps an electric vehicle?

Possibilities are endless. PV panels can make them a reality.

Will PV panels work in partial shade?2023-02-08T19:30:34+01:00

We often hear that “My roof is partially shaded by surrounding properties. PV panels would not work.”

Virtue Solaris offers many solutions for partially shaded spaces. These solutions range from strategic placing of PV panels in such a way so as to maximize exposure to sunlight, to splitting PV circuits into multiple MPPT strings to ensure that one shaded part of the array does not affect the performance of another part, to fitting each solar panel with optimizers that effectively mitigate partial shading effects.

We also have a special offer package specifically catering for such situations.

We do professional shading analysis utilizing specialized software that allows us to estimate precisely the performance of any PV system, even one that is partially shaded.

Will solar panels damage my roof?2023-03-04T13:48:27+01:00

No, solar panels should not damage your roof. Most solar panel systems are designed to be installed on existing roofs without causing any damage. However, it is important to work with a reputable installer to make sure that the system is properly designed and installed, as poor installation practices can cause damage to your roof.
