Solar panel installation

Planning Your Solar PV System

Before installing solar panels, it is essential to understand the basics of solar photovoltaic (PV) systems. These systems convert sunlight into electricity, which can be used directly or stored in batteries. Solar energy is a renewable source available daily, and by utilising it, you can reduce your carbon footprint. To maximise solar energy production in Brunei, it is recommended to install panels at the top of buildings, facing the sky with minimal shading. The ideal angle for panels is lying flat (0°), but a slight tilt of less than 5° can help with rainwater runoff.

System Type and Size

There are two main types of solar systems: Off-Grid and Hybrid. The Off-Grid system is independent and fully reliant on solar energy, requiring batteries to supply power during the night. The Hybrid system combines solar energy with a government power supply as a backup. To determine the size of your system, you need to calculate your power consumption and available roof space. You can refer to your electric bill or add up the kilowatt-hours needed for all appliances to calculate power consumption.

Cost Considerations

The cost of solar power systems in Brunei depends on quotations from companies, the type of system, and its size. Generally, bigger systems have a lower cost per kW. Batteries can account for 30-40% of the overall system cost, and they are typically needed for Off-Grid systems. Installation costs for residential properties range from B$3000 to B$9000 per kilowatt, depending on the system type. Maintenance is usually negligible, but cleaning the panels every 2-3 months is recommended.

Savings and Regulations

Using solar panels can lead to significant savings over time. For example, a 10 kW solar power system in Brunei can save you around $13,665 worth of electricity over its lifespan. Currently, there are no specific regulations governing solar panel installation in Brunei. Companies follow international standards for solar PV systems, and licensed electricians are engaged for installations.

Solar Panel Providers in Brunei

When considering solar panel installation, it is essential to consult with specialised companies. Some reputable companies in Brunei include Everything Solar Brunei, Megawatt Solar Solutions, and Morsjaya Electrical Co Sdn Bhd. These companies can provide consultation, design, procurement, and installation services for solar PV systems.

In conclusion, solar panel installation in Brunei is a feasible option for those seeking to embrace renewable energy. By following the guidelines provided, you can make informed decisions about system types, sizes, and costs, ultimately contributing to a more sustainable future.

Solar panel cost

The cost of a hybrid system, which combines solar energy with a government power supply, is typically B$3000–B$4000 per kilowatt. On the other hand, an off-grid system, which is independent of the electrical power supply and fully dependent on solar energy, costs significantly more at B$8000–B$9000 per kilowatt.

The batteries, which are necessary for off-grid systems and optional for hybrid systems, contribute to a large portion of the overall cost, usually around 30–40%. For example, a 200-watt polycrystalline panel with a single 24v 48-amp battery, charge controller, inverter, connectors, and conduits would cost around BND500–BND600.

It is worth noting that while the initial investment for solar panels may be high, the equipment will pay for itself over time. Additionally, maintenance costs are negligible unless replacement parts are required, and simple cleaning can be done every 2–3 months.

To get an accurate quote for your specific needs, it is recommended to have a solar panel company assess your home or business.

Solar energy efficiency in Brunei

To improve solar energy efficiency, Brunei has implemented several initiatives. The country's first solar power plant, the 1.2 MW Tenaga Suria Brunei photovoltaic power plant, was opened in 2011 and can power around 200 homes. The BSP Energy Transition team was established in 2020 to support the country's decarbonization efforts, and they have since opened a 3.3 MW solar PV plant, which can power 600 homes. This plant uses state-of-the-art solar panel technology with an efficiency of around 20%, and it is designed to capture both the morning and afternoon sun to maximize output.

The Temburong District Office has also installed 255 solar panels on its rooftop, making it Brunei's first solar-powered government building. This system can produce 100 kWp of clean energy and is expected to reduce annual electricity costs by up to $11,000. Additionally, solar streetlights have been installed in Kampong Perdayan and on longhouses in Tutong and Belait's interior, improving energy efficiency in these areas.

For residential use, solar panels can be an efficient and cost-effective option. While the initial cost of installing solar panels can be high, the equipment will pay for itself over time. For an average home, a hybrid system can be a good way to test the waters and see if solar energy can be maintained. Solar energy can be used for light household items such as lights and electrical kettles.

To maximize solar energy production in Brunei, there are a few key considerations. Firstly, the location and angle of the panels are important. Placing the panels at the top of a building, facing the sky with minimal shading, is ideal. Secondly, lying the panel flat (0°) produces maximum energy, and a slight tilt of less than 5° can be made to allow rainwater to run off properly. Finally, the orientation of the panels is crucial – in Brunei, panels installed facing south will be most efficient.

Solar panel maintenance

Solar panels are a great way to save money on your energy bill and reduce your carbon footprint. They are a long-term investment with a lifespan of about 25 to 30 years. To ensure that your solar panels last this long and function effectively, you need to maintain them properly. Here is a guide on solar panel maintenance:

Cleaning

Solar panels require minimal maintenance, but it is important to keep them clean. Dirt, debris, dust, leaves, and bird droppings can accumulate on the panels, especially during storms, long dry periods, or when trees are shedding leaves. This buildup can reduce the amount of sunlight that reaches the panels, affecting their energy output. It is generally recommended that you clean your solar panels about two to four times a year, depending on the weather conditions and your location. If you live in an area with a storm season or experience prolonged periods without rain, you may need to clean your panels more frequently.

When cleaning your solar panels, always turn off your solar power system first. The best way to clean the panels is by spraying them with lukewarm water from a hose or bucket. Do not use soap, cleaning agents, or a pressure washer, as these can damage or streak the panels. For heavier deposits, you can use a non-abrasive, microfiber cloth to wipe down the panels after spraying them. If you need to access the roof, always use a safety harness or take other precautions to prevent falls. Alternatively, you can use a telescopic pole with a microfiber cloth attached to clean the panels from the ground. Avoid cleaning the panels on a sunny day, as the water can evaporate quickly and leave smudges.

Monitoring

You can monitor the health of your solar panels by periodically checking for dirt and debris buildup. Over time, it is natural for solar panels to decrease in performance, but if they are underperforming, it may be a sign that they need cleaning. Some solar companies offer mobile apps that allow you to monitor the energy production of each panel in real time and alert you to any unusual dips in performance.

Inspections

In addition to cleaning, it is recommended to schedule an annual inspection with a solar specialist. They can ensure that your panels are in good condition and working properly. They will also inspect wires and connections to make sure they are in working condition and have not been damaged by critters.

Maintenance Costs

The cost of maintaining solar panels is typically low. An annual inspection can range from $150 to $300 per visit. If you prefer to hire someone to clean your panels for you, it may cost around $150 per cleaning. Some solar panel companies offer free mobile apps to monitor usage, while others may charge a small fee for these apps. It is important to consider these maintenance costs when calculating the total cost of owning solar panels.

Warranties

Solar panel warranties are important to protect your investment. Manufacturer warranties typically cover solar inverters, solar batteries, and workmanship and material defects. The panel warranty, also known as an equipment or materials warranty, covers the actual equipment. Installer warranties include a workmanship warranty, which covers any damage or defects during the installation, and a production, performance, or power output warranty, which guarantees a certain level of energy output over time. A weatherization warranty can also protect your roof and panels from leaks or damage caused by wind or rain. These warranties usually last for a limited period, typically 10 to 25 years, and vary depending on the manufacturer, installer, type of panels, and location. Be sure to read the fine print and understand what is covered. Proper maintenance of your solar panels may be required to keep your warranty valid.

Extreme Weather

Solar panels are designed to withstand extreme weather conditions, including hail, snow, ice, and wind. They can even survive hurricanes, as evidenced by their limited damage during Hurricane Florence in 2018. However, they are not completely indestructible, and on rare occasions, they can be damaged by severe weather events such as hail, hurricanes, tornadoes, or lightning. A good warranty will cover any necessary repairs or replacements due to weather damage.

Heat

Ironically, the type of weather that most commonly affects solar panel performance is heat. When the temperature rises above 77°F (25°C), panels lose efficiency by approximately 1% for each degree increase. To mitigate this, you can elevate the panels a few inches above the ground or roof to allow for air circulation and help cool them down.

Repair and Replacement

If your solar panels need repair or replacement, it is best to hire a professional, especially if they are still under warranty. Contact the company that installed your panels, and they will assess the situation and either fix the problem or replace the panels. If your panels have sustained physical damage, this is typically covered under a separate equipment warranty.
