FAQs

How much does a solar panel installation cost in the Philippines?

Cost depends entirely on your monthly electric bill and the system size you need. A small 1kW to 3kW residential setup can range from ₱80,000 to ₱250,000, while larger 5kW to 10kW systems scale higher but offer faster investment returns.

What is the difference between Grid-Tied, Hybrid, and Off-Grid solar systems?

Grid-Tied systems connect directly to Meralco/electric cooperatives to lower daytime bills but turn off during brownouts for safety. Hybrid systems use batteries to power your home during brownouts while remaining grid-connected. Off-Grid systems rely 100% on batteries and are independent of power lines

How much will I actually save on my electricity bill?

Most residential and commercial properties reduce their daytime electricity bills by 60% to 80%. The exact amount depends on how much energy you consume while the sun is shining.

What is Net Metering and how does it work?

Net Metering is a government program where your local utility provider (like Meralco) buys the excess electricity your solar panels produce. They credit this amount to your monthly bill, driving your costs down further.

Is your company legally registered and compliant?

Yes, we are a fully SEC-registered corporation, and all our installations comply strictly with the Philippine Electrical Code (PEC) and local utility standards

Will my solar panels work during a brownout?

If you have a standard Grid-Tied system, it will automatically shut off during a brownout to prevent electrocuting line workers. If you require uninterrupted power during blackouts, we highly recommend our Hybrid systems with battery backup

What happens on cloudy or rainy days?

Solar panels still generate electricity during overcast weather by absorbing ambient, diffused sunlight. However, system production will drop to about 10% to 25% of its peak capacity compared to a clear, sunny day.

How long do solar panels and inverters last?

Tier-1 monocrystalline solar panels are highly durable and come with a performance warranty lasting 25 years. Hybrid and grid-tie inverters typically carry a warranty of 5 to 10 years depending on the brand

How much maintenance do solar panels require?

Solar systems require minimal maintenance because they have no moving parts. We recommend professional cleaning and an electrical health check once or twice a year to clear away dust, leaves, and bird droppings that block sunlight

Can a solar pump handle deep well agricultural irrigation?

Yes, we install high-head DC solar submersible pumps with MPPT controllers. They pull water directly from deep underground aquifers using zero fuel, completely eliminating diesel expenses for farms.
