Solar Power System for Home in Sri Lanka

Sri Lanka, blessed with abundant sunlight throughout the year, is an ideal location for generating solar power. As the country grapples with frequent power cuts and rising electricity costs, more and more Sri Lankan homeowners are realizing the long-term benefits of installing rooftop solar systems to meet part or all of their energy needs.

Overview of Solar Power in Sri Lanka

The average solar radiation in Sri Lanka ranges from 4.5 to 6.5 kWh per square meter per day. This is sufficient to generate significant solar energy through photovoltaic (PV) panels, even with limited roof space. Currently, Sri Lanka has over 60 MW of installed solar PV capacity, but this is just a fraction of the country’s true potential, according to energy experts.

With net-metering introduced in 2016, homeowners can now install grid-connected solar systems and export excess power to the national grid. This helps offset nighttime use and leads to monthly savings on electricity bills. Solar system costs have also declined by 50% in the last 5 years due to improving technology and economies of scale.

The Sri Lankan government offers several incentives for citizens to go solar:

  • Net metering scheme up to 10 kilowatts (kW)
  • Concessional loans covering up to 80% of rooftop solar installation costs
  • Customs duty waivers on imported solar panels and accessories

Reputable solar companies like Ouyad Solar handle all permitting, approvals and paperwork for these incentives as part of their turnkey installation service.

Benefits of Installing a Rooftop Solar System

Investing in a grid-connected solar PV system brings numerous benefits for Sri Lankan households:

Financial Savings

By reducing monthly electricity bills by 50-100%, rooftop solar starts paying for itself within 4-6 years. Thereafter the system continues to provide free electricity for another 10-15 years. This gives a healthy return on investment of 15-25% over its lifetime.

Backup Power During Outages

Solar systems come with battery backup to provide power even when the grid fails. This energy security is invaluable given the frequent power cuts faced by the nation. Critical loads like lights, fans, TVs and phone chargers can run for hours using the solar batteries.

Reduced Carbon Footprint

Generating your own solar electricity reduces annual carbon emissions by 3,000-5,000 kg per average household. This helps protect the environment for future generations.

Enhanced Property Value

A rooftop solar system can boost your home’s resale value. Eco-conscious home buyers are willing to pay a premium for properties with existing solar installations.

Is Your Home Ready for Solar Power?

Before installing a solar PV system, it’s important to evaluate if your home is truly ready to harness the sun’s energy. Ideal candidates for rooftop solar have:

  • South or west facing rooftops without shade from trees or other buildings
  • Reinforced concrete flat roofs or roofs made of metal/tile sheets that can bear the additional weight of solar panels
  • Sufficient space for a PV system size of 3-10 kW depending on household energy usage
  • An updated electrical system safely handle solar connections and net-metering

Reputable solar installers like Ouyad Solar offer free site assessments to analyze rooftop viability and customize a system design for optimal productivity.

How Does a Grid-Connected Solar Power System Work?

A rooftop solar system has three key components:

Solar PV Panels → Inverter → Electricity Meter

Solar panels capture sunlight and convert it into DC electricity. This DC power is optimized by the inverter into AC power for household use and grid export.

Net-metered bi-directional meters track both grid consumption from and solar electricity exported to the grid. Monthly credits are provided for surplus solar units exported, reducing household electricity bills.

Ouyad Solar uses high-efficiency mono PERC solar panels combined with premium inverters like Huawei, Sungrow or Solis. This ensures maximum productivity from the rooftop space available.

Their experienced installers secure the solar panel mounting structure, integrate the components safely, and handle all final connections and commissioning. You just need to switch on your solar power system to start benefiting for 25+ years!

Solar System Sizes, Costs and Incentives in Sri Lanka

Typical rooftop solar system sizes for Sri Lankan homes range from 3 to 10 kilowatts (kW). The exact capacity is customized based on your available roof space and average household electricity consumption.

For a 5 kW solar system, you can expect an upfront investment of around LKR 800,000 to 900,000. However, with concessional financing from government approved banks, only 20% of this cost needs to paid upfront. The balance 80% is covered by a loan with 8-10 years tenure at very attractive interest rates.

You can claim tax credits up to 35% and full import duty exemption on your solar power system under Sri Lanka’s net-metering regulations. Reputable companies handle all the paperwork for these incentives.

In addition to these financial incentives, the Ceylon Electricity Board (CEB) also provides a generous solar feed-in tariff for excess units exported to the grid. As of 2022, this tariff rate is LKR 22 per unit for systems below 10 kW.
