“Net metering is an electricity policy for consumers whoown renewable energy facilities (such as solar power)which allows them to use electricity whenever neededwhile contributing their production to the grid.”

Net-metering allows customers of Distribution Utilities(DUs) to install an on-site Renewable Energy (RE) facilitynot exceeding 100 kilowatts (kW) in capacity so they cangenerate electricity for their own use. Any electricitygenerated that is not consumed by the customer isautomatically exported to the DU’s distribution system.

1. To End-Users

Generate savings Protect end-users against rising electricity prices

2. To the Environment

Helps mitigate climate change

3. To the Economy

Contribute in lessening the country’s dependence on costly importedfossil fuels.

Section 10. Net-metering for Renewable Energy. - Subject to technical considerations andwithout discrimination and upon request by distribution end-users, the distributionutilities shall enter into net-metering agreements with qualified end-users who will beinstalling RE system.

The ERC, in consultation with the NREB and the electric power industry participants, shallestablish net metering interconnection standards and pricing methodology and othercommercial arrangements necessary to ensure success of the net-metering for renewableenergy program within one (1) year upon the effectivity of this Act.

1. Filing of Application Go to DU and request to participate in net-metering program. Upon receipt of request, DU will ask you to submit the following

documents:Net-Metering Application Form Identification DocumentDetailed Planning Data List of Certified Equipment Plant Parameters Form

After 10 business days, DU will issue acknowledgement receipt with feedback on whether or not the application is complete.

2. Technical Evaluation Conduct Distribution Impact Study (DIS)

Scope of the Study Estimated Time of DIS Completion DIS Fee

3. Inspection With the conclusion of the technical evaluation phase, the DU

finalizes the design of the interconnection facilities based onthe results of the DIS and / or DAS, along with thecorresponding project costs, if applicable. This stage includesan inspection of the Service Entrance depending on the meterset-up (2 uni-directional meter or single bi-directional meter).A Certificate of Final Electrical Inspection (CFEI), to be obtainedfrom the city or municipality, may be required on a case-to-case basis.

4. Energization Once the construction is completed, the applicant’s installed

facilities will undergo testing and commissioning to bewitnessed by the DU. Commissioning will include inspection ofthe system components and functional tests to ensurecompliance with the Net-Metering Interconnection Standards.

- Solar Roof Tops in the Philippines can be avail from your Installer, but there are some important points to consider when planning and purchasing a small PV System intended for Own Consumption.

• Choosing a Good PV Installation Company

• Selecting Components for Solar Roof Top

• Modules to Buy

- Crystalline Modules

- Thin Films

• Choosing Inverters

• Selecting Mounting Systems and Warranty

• Sizing of the PV System

A. Choosing a Good PV Installation Company

The Installer is able to explain the working of the PV System in simple words and in a comprehensive way.

The Installer provides electrical plans and other documents required for LGU Electrical and Building Permits.

The Processing of permits are included in the services.

the offer includes the delivery of all required components and services to produce electric power and feed it into the grid.

A. Choosing a Good PV Installation Company

Grid-Connection, and Commissioning of the PV Plant. in other words, a turn-key installation.

the client stipulated to provide any item. Optional and Mandatory items distinguished and

terms and conditions of the contract The installer observe current applicable standards and

guidelines and know compliance standards set by the electrical and distribution codes valid in the Philippines

payment conditions : are instalments included ?

B. Selecting Components for Solar Roof Top

B. Selecting Components for Solar Roof Top

Check if the module passed the design qualification and type approval.

Crystalline Modules

Manufactured for Maximum Energy yield per meter squared ( m2 ) Mostly with aluminium profile frames which protects glass edges,

facilitates mounting, improves statics of modules and can be used for fixation on mounting structures.

Most frames are produced with mounting holes and holes for water discharge.

B. Selecting Components for Solar Roof Top

Thin-Film Modules

Modules with cadmium (CdTe) and amorphous silicon solar cells (a-Si) are mostly widely used.

Other cell types contain copper (as CIS/CIGS modules) As less semi-conductor material is needed, the production of

thin-film solar modules become cheaper and the selling price drops significantly.

Reminder : Thin-Film modules have a lower efficiency that c-Si modules. Therefore larger area is needed for the PV Installation.

Often used in facades or, as they weigh less and can be produced in flexible forms, integrated in different building forms.

B. Selecting Components for Solar Roof Top

Test Specification

Crystalline Modules : choose the modules with standard IEC 61215 which comprises the examination of all parameters linked to ageing of PV modules and describes various qualification tests based on artificial load of the materials (radiation, thermal and mechanical testing).

Thin-Film Modules : choose the modules with standard IEC 61646, where additional test procedures are done to adapt to special properties of thin-film technologies.

C. Choosing Inverters

Place of Installation

As much as possible, the inverter should be installed near the house meter. Shorter DC cabling cuts system loss of solar power.

Inverters get slightly warm during their operations. To achieve higher performance, there should be adequate ventilation.

Always Comply with the external conditions demanded by the manufacturer, particularly permissible humidity and ambient temperature

C. Choosing Inverters

USEFUL TIPS

1. Ensure adequate ventilation2. Consider range of permissible ambient temperature

for inverter (avoid power limitation due to high temperature.

3.If an inverter is mounted outdoors it has to be protected against rain and insolation.

4. pay attention to local high tide levels.

D. Selecting Mounting Systems and Warranty

Unlike in the past, manufacturers now offer easy to installmounting systems for flat roofs. For large roofs on industrial andcommercial buildings, frames are now generally lightweight,aerodynamic, self-supporting, and without roof penetrationchallenges. These features are ideally suited for roofs withmembrane or bitumen surfaces as they represent a slight additionalload to the roof.

Most Inverters have 10-yearLimited warranty.

E. Sizing of the PV System

• Do I need a small PV Systems ?• Can I install Large PV Systems up to 100 kWp ?• How do I recognize a good offer ?

.> Demand a Module layout plan with proposed location ofmodules and wiring

.> Demand a block diagram of whole PV System.

.> Check if all necessary items are included

.> Demand information about statically testing of offeredmounting system provider and client. Demand more detailsif this information was not provided.

.> You can also ask for advice in the internet, e.g. atwww.photovoltaicboard.com
