In 2013 the solar roof top market in the Philippines is expected to double in size from 2.5MW to 5MW. The passing of the net-metering rules and interconnection standards enabling all on-grid end-users to install a solar roof top will further boost the market as now the regulatory framework has been set. The following examples of solar roof top installations give an overview of different applications in the residential, commercial and industrial setting.
11.76 kWp - Orphanage installation, Southern Leyte
Project overview
This project is a 11.76kWp residential installation at an orphanage in Southern Leyte. Consisting of 48 CNPV 245 watt-peak polycrystalline modules, a light weight aluminium Intersol mounting system by Donauer Solartechnik, and a display of 2 SMA Sunny Mini Central Inverters (6000 Watts each), this system is designed to maximize the given roof space of the orphanage while utilizing the future benefits of net metering to ultimately lower the operations of cost of the orphanage.

Project site
Southern Leyte
Project setup
A study of the consumption pattern of the facility showed that an average of 30% of the Solar production is used by the facility on the weekdays, due to the children leaving the orphanage during school (Although increasing significantly during weekends), amounting to an estimated savings of Php 3,200.00 per month. The remaining 70% is designed to be fed out to the grid and will benefit the facility by an estimated Php 3,700 per month (When Net-metering is implemented by the Southern Leyte Cooperative, which is the local distribution company that has given permission to connect to their grid before installation).
Key facts and figures
The layout of arrays follows an East-West facing design (24 modules 90º East at 20º inclination; 24 modules 90º West at 20º inclination) while the inverters are set on Single-phase grid at 230Volts. Over the first year of operation, this system has a yield of 1350 kWh per kWp, or 15,876 kWhs a year.
22.05 kWp - Commercial/office building installation, Quezon City
Project overview
The purpose of this 22.05kWp installation of the solar power system is to produce supplementary power to the entire 4-story commercial/office building during weekdays while eventually taking advantage of the Net-Metering scheme on the weekends.
The project partners
Name of solar installer: MATEC
Project Setup
The layout of the array was made to maximize the roof space given by the building, which was specifically designed to easily install the largest possible grid-tied system for the given area. The entire array will be placed on a South Facing roof at a 15º inclination on a rib-type metal sheet, allowing for a quick installation and an optimal yield. An inverter room was provisioned on the top floor to house the 4 single phase inverters designed to connect to the building’s 3 phase Delta grid (230V Line-Line), which is a common grid constellation found in Manila.
Key facts and figures
Consisting of 105 Evergreen 210 watt-peak polycrystalline modules, a simple yet robust mounting system designed by Schletter, and a display of 4 Single phase grid tied Inverters by SMA (2 x SMC 7000, 2 x SMA 4600).
Over the first year of operations, it is expected to produce close to 31,750 kWhs of energy. Once the building is in full operation, it will utilize an anticipated 71% of solar power produced while the remaining 29% will be fed into the grid, mainly during the weekends, through Net-metering upon full implementation and completion of the building.
0.49 kWp - Residential installation
Project overview
The On-Grid Solar PV was installed with three (3) components namely: 1) the PV module; 2) the Micro-inverter and 3) the Power Manager.
The project partners
Name of solar installer: Solarus Partners Inc
Project Setup
Two panels were put on the roof. Each panel is rated at 245Wp, totalling 490kw capacity for the entire system. Since the system uses micro-inverters, one unit of micro-inverter was attached per panel. The mounting structure is made of fiberglass to avoid corrosion. Its lightweight characteristics reduce strain on the roofing structure. The installation was quick and easy. The frame was bolted on the roof in less than a day; the actual fitting of the solar panels on the frame took about an hour only.
Key facts and figures
Last July 2012, the Solar PV 460W modules were installed with a cost of Php 78,000 or Php 170/Wpeak. With an 803 kWh annual production (estimate) and using a rate of P11.91/kWh avoided cost (without net metering), the simple payback of this project is 7.42 years. The 460W Solar PV can supply 3 x 6W CFL, a 14 inch TV and a 228W refrigerator. On a rainy month of August 2013, the average output was 2.20 kWh/day.
