Most rooftop solar panels sold in the Philippines today are 113.4 cm wide and 172 to 247 cm long. A 600 W panel is about 2.28 m × 1.13 m (7.5 × 3.7 ft) and weighs around 31 kg. Here's a size chart from real datasheets, how much roof space each kilowatt needs, and worked examples showing why a bigger panel doesn't always fit more power on your roof.
Most sound roofs in Leyte and Biliran can carry solar panels: about 13 kg per square metre with rails. The harder part is wind. Here's what the NSCP and the makers' manuals say about weight, uplift, fixings for longspan, concrete deck and tile roofs, and where leaks start.
Lightning rarely hits a house directly, but nearby strikes and surges on the line kill inverters every thunderstorm season. Tacloban averages 108 thunderstorm days a year, most of them from May to October. Here's where surge protectors (SPDs) go on a solar system, what they cost (about ₱500 to ₱1,000 each), what the Philippine Electrical Code says about grounding, and when a lightning rod is worth it.
Don't dump cracked or retired solar panels in the barangay trash. Under DENR rules they sit in the same hazardous WEEE class (M506) as other e-waste. This guide walks through RA 6969, DAO 2013-22, why RA 11898's EPR law does not cover PV modules, what UP CIDS projected for Philippine panel waste in April 2026, and a practical after-typhoon checklist for Leyte and Biliran homeowners — without inventing a local recycling plant that does not exist yet.
We read each bank's own pages on 17 October 2026. BPI and Security Bank have a named Solar Mortgage, BDO and RCBC finance solar through home loans, personal loans or card instalments, and Landbank has no solar loan for individual homeowners. Minimums start at ₱200,000 to ₱1,000,000 and most need a house or car as collateral, which is more than many 3–5 kW systems in Leyte and Biliran cost. Terms, fees, worked examples and when Pag-IBIG is the better fit.
We ran the European Commission's PVGIS model for Naval, Tacloban and Ormoc at every tilt from flat to 35° and eight roof directions. The best angle is only about 10–12°, facing south (a little east of south). A flat or east-facing roof loses just 1–4% a year, a west roof 3–6%, but a steep north-facing roof can lose up to about 20%, and half its output in December. Tables, three worked examples and what to ask your installer.
On 16 October 2026, Philippine sellers listed solar roof and wall ventilators from about ₱10,800 (Solar Hub 30 W wall) to ₱23,800 (Kool Vents 40 W). A Florida Solar Energy Center case study found two solar attic fans cut peak attic heat by over 20°F and air-con use by about 6% — useful, but not a huge bill cut. For Leyte and Biliran metal roofs and typhoon season, the bigger questions are roof sealing and whether insulation or a radiant barrier would do more. Prices, research and install notes below.
Yes, you usually pay 12% VAT when you buy solar panels from a VAT-registered seller. A 2022 BIR regulation says a buyer who isn't VAT-registered can claim that VAT back as a credit against the same year's income tax. Your town or province may also put the system on a tax declaration for real property tax. The big RA 9513 incentives (tax holidays, 0% VAT, special realty rates) are for DOE-registered RE developers, not ordinary homeowners. Here are the laws, a worked example and who to ask in Biliran and Leyte.
Rain helps, but coastal salt, typhoon dust and bird droppings still cut solar output. Manufacturer manuals say soft tools, cool panels and no walking on glass. Here's how often to clean in Eastern Visayas, what Metro Manila crews charge, and why we couldn't find a published Leyte service rate.
Rooftop solar can usually be insured as part of your house under a Philippine home or fire policy, but only for the perils you bought and up to the value you declared. We read the policy wording and brochures from BPI/MS, FPG, Malayan and Standard Insurance: why fire-only cover misses typhoons and floods, the 2% typhoon deductible on the whole house, the clause that excludes electrical damage to inverters, how under-declaring cuts a claim, and what to ask your insurer before typhoon season in Leyte and Biliran.
LEYECO II publishes a six-phase net metering process, a request form and a hosting-capacity table. Here's how to use them, what the 2025–2026 national rules change, what you'll pay, how long it should take, and what a net-metered LEYECO II bill looks like.
At 2026 rates, our example homes on BILECO and LEYECO II pay back a solar system in about 2.3 to 4.7 years. If rates fall back to May 2026 levels, that stretches to 3.3 to 6.7 years. Here's the math for three households, grid-tie vs hybrid, and the cases where solar doesn't pay.
LEYECO II's September 2026 residential rate is ₱14.0488/kWh before VAT, its highest in the 21 months we tracked. Here's every monthly rate from January 2025, what's inside the rate, sample bills at 100–300 kWh, how it compares with BILECO and other Eastern Visayas co-ops, and honest solar math.
A practical checklist for homes that already have solar. Charge batteries when Signal No. 1 goes up, take photos, move gear above flood level, stay off the roof, and after the storm check from the ground and treat panels as live. Includes PAGASA's wind signal scale and what panel datasheets actually rate for.
