For example, a 3 kW photovoltaic system may produce enough energy for a small house, while a 10 kW system may be necessary for a larger home or a business.

Ensys study: Prosumers invest an average of 35,000 lei in solar systems

For example, let’s consider the LONGi LR5 410W photovoltaic panels with an efficiency of 21.5%, commonly used by ENSYS. These panels have a power degradation of less than 2% in the first year and 0.55% in years 2-25. Additionally, let’s assume that the panels are installed under ideal conditions, with a south-facing orientation and perfect tilt.

1. A 3 kW photovoltaic system: This system would require approximately 8 410W LONGi LR5 panels. Under ideal conditions, such a system could produce an average of about 3,600 kWh per year.
2. A 5 kW photovoltaic system: This system would require approximately 13 410W LONGi LR5 panels. Under ideal conditions, such a system could produce an average of about 6,000 kWh per year.
3. An 8 kW photovoltaic system: This system would require approximately 20 410W LONGi LR5 panels. Under ideal conditions, such a system could produce an average of about 9,600 kWh per year.
4. A 10 kW photovoltaic system: This system would require approximately 25 410W LONGi LR5 panels. Under ideal conditions, such a system could produce an average of about 12,000 kWh per year.

These values are estimates and may vary depending on several factors, including weather conditions, shading, geographic location, etc. For a more precise assessment of your specific needs, we encourage you to contact an ENSYS consultant by accessing the dedicated configurator – click here.

No less than 55% of a home’s energy consumption is used for heating. The 45% difference is split between lighting, hot water and appliances.

Finding an optimal but also economical temperature for the home can turn into a long process of experimentation. We created this guide to help you. Thus, you too will be able to find an optimal temperature for the comfort of your family, taking care at the same time of electricity consumption.

The temperature in the home depending on the season

Considering that our body is used to climate changes in each season, the temperature in the home must also be changed depending on the season.

While the ideal temperature in winter is 20-22 ℃, in the warm season the optimum temperature is between 22-24 ℃ (about 10 degrees less than the outside temperature).

Maintaining optimal temperature values: Benefits

These are some of the benefits of maintaining an optimal temperature in the home:

• Improved mood, physical and mental health;
• Deep and quality sleep;
• Low energy consumption.

Efficient use of the heating system: Practical Guide

Follow these tips to make sure you don’t pay higher gas and electricity bills than you need to:

• Always close the room doors;
• Do not cover radiators;
• Install reflective panels behind radiators to direct heat into the room. In this way you can save up to 2-3% of the total energy consumption of the home;
• Thermally insulate your home;
• Use smart thermostats that can be set so that the home is not heated during certain time intervals or days, when no one is at home;
• Periodically check the heating system.

Keep in mind these useful tips to make your home the perfect place to relax, at optimal administrative costs.

If we take thermal efficiency and costs into account, underfloor heating can be the best solution for those who want increased comfort in their homes. However, because not many know the advantages of this way of heating, all kinds of myths have appeared around this subject, some of which are far from the truth.

These are the most well-known myths regarding underfloor heating:

1. Underfloor heating is more expensive than radiator heating.

Although the price of installing an underfloor heating system is about 30% higher than traditional radiators, the investment pays for itself in a relatively short time. Considering that an underfloor heating system is more thermally efficient and easier to maintain, it is impossible for the monthly bills to be higher compared to a classic heating system.

2. A house with underfloor heating never heats up.

It is true that an underfloor heating system does not produce as much heat as radiators, but it certainly creates a pleasant ambient environment. The system distributes the heat evenly over the entire surface of the floor, so the room temperature can even reach 25 ℃.

3. Technically speaking, underfloor heating is an electric heating system.

The floor system runs on electricity, but the hydraulic system runs on hot water and central heating. There is also the option to connect the underfloor heating system to a heat pump. Heat pumps require little or no electricity as they rely mainly on renewable energy. As underfloor heating operates at a fairly low constant temperature, the option of adding a heat pump to your underfloor heating system is an ideal option.

4. Underfloor heating systems take more time to warm up the living space, so the temperature remains not constant.

While electric underfloor heating operates almost as quickly as a radiator, the hydraulic system works a bit slower. But that doesn’t mean you have to endure low temperatures.

It is essential to understand how to configure the system to best fit your lifestyle and maintain a comfortable temperature in your home. For example, if you have a hydraulic system, you can adjust the settings to ensure that the room temperature decreases by a maximum of 3 ℃ during the night.

5. Underfloor heating is unhealthy.

Underfloor heating prevents the circulation of dust particles that can lead to allergies or illnesses. Homeowners can also benefit from better humidity and a healthier environment, free of mites and mold, which is especially helpful for those with allergies or respiratory issues. Therefore, underfloor heating not only does not harm health but is even recommended for sensitive individuals.

With the help of solar panels installed on your house’s roof, you can save a significant amount of money every month. They capture energy from the sun and convert it into electricity for all the consumers in your home.

But you might be surprised to learn that not only your home can benefit from the electricity generated by photovoltaic panels. You can also save money and protect the environment by using solar panels outside the house.

Discover 9 other ways you can use solar energy outside the house:

1. Mobile Phones

There are phone cases available on the market with a small photovoltaic panel installed on the back. When this panel is directed towards the sun, it can generate electricity and charge your phone. This type of case is ideal for those who spend a lot of time on the go or outdoors.

2. Navigation Systems

It may be hard to believe, but there are already electric boats and yachts fully powered by solar energy. They do not need any fuel or oil because the photovoltaic panels they are equipped with power both the engine and onboard devices, including the navigation system. We can say that the industry is rapidly developing, and there are already 100% electric yachts and ships capable of covering considerable distances.

3. Camping Equipment and Accessories

To use certain electric equipment and accessories for camping, you usually need to rely on the vehicle’s power supply while traveling. However, there are plenty of eco-friendly camping items available, such as tents, charging stations, cooking stoves, and heating systems.

4. Lanterns

You can say goodbye to expensive and polluting batteries for your lantern. There are already many lanterns that can store solar energy during the day to be used when needed.

5. Portable Chargers

While these chargers with photovoltaic panels may not have the power to operate household appliances, they can charge laptops, cameras, or tablets. Many of these chargers can be attached to other accessories (bag, backpack, purse) to capture as much solar energy as possible when you are outdoors.

6. Public Transportation

More and more cities around the world, including Romania, have electric public transportation (trains, subways, buses, trams), either partially or entirely.

7. Public Lighting System

Cities, commercial spaces, and residential areas can also benefit from solar energy. All that is needed is a small photovoltaic panel installed for each lighting post.

8. Traffic Signs and Billboards

Any traffic sign or advertising billboard that uses intermittent or background lighting can be powered by solar energy. This would reduce costs and the carbon footprint on the environment.

9. Pool Heating

Photovoltaic panels can be easily installed on the pool’s cover to heat the water. This way, you can enjoy your pool during the summer months without worrying about the costs associated with a traditional water heating system.

The number of Romanians who own a caravan or choose to spend their holidays on four wheels is increasing from one year to the next. Certainly the pandemic we went through influenced this trend, during which the caravan represented an excellent alternative to spend a relaxing holiday in the middle of nature, at the sea or in the mountains.

If you own one or more campers or are thinking of buying one, you’ve probably wondered if a solar panel system would be a good investment to cover your electrical needs while on vacation or hiking.

In this article we will show you how to calculate the number of solar panels for a caravan, but also what other components you need

How do solar panels produce energy for a caravan?

Solar panels for caravans function like any other photovoltaic panels, consisting of silicon solar cells. Silicon is an excellent semiconductor of electricity while maintaining an electric imbalance, necessary to create an electric field.

How many solar panels are needed for a caravan?

Just like with solar panels for homes, the number of solar panels, inverter power, and the number of batteries for a caravan depend strictly on the consumption needs.

To answer this question, the simplest way is to make a list of all electrical appliances (consumers) you use when you are on vacation with the caravan, along with their power expressed in watts. By knowing the total power of all consumers, you will determine the capacity needed for the solar panel system. It is not necessarily important to know the exact number of panels required but rather the ratio between the total system power and your consumption needs.

After creating the list of consumers, estimate the approximate number of hours each appliance is used during a typical day. The calculation is straightforward:

Device Power x Number of hours used = Consumption in watts

By calculating the total, you will find out how many watts you consume on an average day and the power that needs to be generated by the solar panel system.

To help you, below is a rough list of the most common consumers in a caravan and their approximate consumption:

The best solar panels for a caravan

Monocrystalline panels are the most recommended, not just for homes but also for caravans, due to their efficiency, especially considering the limited installation space available in this case.

You might have heard of the existence of flexible panels (monocrystalline or polycrystalline) that are thinner than traditional panels and can bend up to 30 degrees. However, traditional panels are still more efficient and durable.

Other necessary components

In addition to solar panels, you will also need the following components:

• Solar Controller: Its role is to protect the batteries by controlling the power they receive. Among the two models available on the market, MPPT is recommended over PWM due to its higher efficiency.
• Solar Batteries: They store the energy produced by the solar panels. Lithium batteries are generally more expensive compared to gel batteries, but they are more powerful and have a longer lifespan.
• Solar Inverter: Its role is to convert the direct current produced by the panels into alternating current (220V or 240V), which is then transmitted to the fuse box and distributed to electrical consumers.
• Fuses: They distribute electricity to the appliances and accessories in the caravan, protecting the cables from power surges or other malfunctions.
