Benefits of going solar for landed houses in Singapore

Solar panels reduce your electricity bills

Making solar your top priority when you renovate your house will be a huge step in reducing your monthly bills. To be able to comfortably bask in the solace of your own home, cranking on the AC in the hot and humid climate of Singapore is inevitable at times. Coupled with the increase in the electricity tariff over the years, having solar panels installed for landed houses seems like an obvious  solution to reduce your electricity bill.

Installing solar panels on your roof will lead to long-term savings. The solar electricity generated will feed into all of your household electrical appliances during the day. The cost of solar electricity generated is also usually more than three times cheaper than the electricity tariff. Solar panel installation will save you a ton from purchasing electricity from the grid during the day!

Environmentally friendly source of electricity

In Singapore, 95% of electricity is fueled by natural gas with the remainder generating electricity from diesel, waste incineration, coal and biomass. To minimize environmental impacts, going solar is becoming popular amongst landed home owners because solar is the most practical clean energy solution. Homeowners can make use of their unutilised roof space to generate electricity to power their day to day lives.

Do you know that a tree absorbs approximately 25 kg of carbon dioxide per year? In Singapore, the average carbon dioxide emissions emitted per unit of electricity generation is 0.4085 kg/kWh. A bungalow consumes around ~2250 kWh on average every month. That produces ~920 kg of carbon dioxide and requires ~37 trees to offset those emissions. This can be significantly reduced by installing solar panels.

Solar PV technology advancements

Solar cells were first developed in 1883 when Charles Fritts, a New York inventor, created a low impact solar cell by coating selenium with a thin layer of gold. With more than a decade of research and development, modern solar cells are able to transform radiant energy from the sun into electricity at an incredible efficiency.

Today, it is common to find solar panels with conversion efficiency exceeding 20%. With the technology advancements and commercialisation of solar panels, solar panels are more affordable now than before. Solar is also the least expensive and cleanest form of renewable energy available. It is especially adaptable for the Singapore climate which is sunny all year round.

Solar panels are low maintenance

Solar panels are typically mounted on rooftops with aluminum and stainless steel fixtures. The main components are solar panels, inverter and mounting structure, which do not involve complex mechanical operations. There are zero moving parts in a rooftop solar system. Therefore, the likelihood of wear and tear of the solar system is minimal and almost negligible. Preventive maintenance is recommended at a frequency of once a year.

Solar panels are designed to withstand various weather conditions for all-seasons countries which include rain, snow and even hail. The solar cells are encapsulated in strong, durable materials such as tempered glass and aluminum frames. They are resilient to damages in many environments. With some occasional rain, it will help to clean the solar panels naturally by washing away dust and debris.

Solar panels have long lifespan

Solar panels have a long operational lifespan around 30 years. Tier-One manufacturers offer 25-30 years performance warranty for solar panels. The performance warranty also known as linear power warranty guarantees that the solar panels remain efficient with a linear degradation over the warranty period.

By choosing a reliable solar inverter which comes with built-in monitoring capabilities, onsite inspections are rarely required. This inverter feature allows the system owner and the installer to remotely monitor the solar system at all-time, ensuring quick identification of any potential issues and maintenance needs.
