types of solar installation and how it works.

1. SOLAR
INSTALLATION
PROJECT PROPOSAL
for
Members

2. Objective
• To provide solar energy solutions
that are sustainable, cost effective,
economical, and environment-
friendly to the Members (for
Residential and Commercial
establishments).

3. What is SOLAR ENERGY?
• Usable energy generated from
the sun in the form of electric or
thermal energy.
• It can be captured with various
technologies, primarily Solar
Panels.
Residential
Commercial

4. The “Photovoltaic Effect”
Photo = light
Voltaic = produces voltage
• Photovoltaic (PV) systems the mechanism by which
silicon solar panels harness the sun’s energy and
generate electricity.
The photovoltaic process works through the following
broad steps:
1. The silicon photovoltaic solar cell absorbs solar
radiation.
2. When the sun’s rays interact with the silicon cell,
electrons begin to move, creating a flow of electric
current.
3. Wires capture and feed this direct current (DC)
electricity to a solar inverter to be converted to
alternating current (AC) electricity.

5. Types of Solar Design
1. Grid Tied System
2. Off Grid System
3. Hybrid System

6. Types of Solar Design
1. Grid Tied System
- A solar energy system that is
connected to the electrical grid
(Meralco).
- It helps turn sunlight into
electricity by using solar panels
and a power inverter, along
with other small components.
- Solar energy power is used
during daytime, however it
doesn’t work during night time.
- No batteries needed.

7. Types of Solar Design
2. Off Grid System
- Battery based solution/Stand Alone
Power System that provides power
during night time and during
power outages.
- Not connected to the electricity
grid (Meralco) and therefore
requires battery storage.
- Act as a Generator replacement.
Recommended for areas with
frequent power interruptions.
- More expensive than Grid-tied by
50% due to battery purchase.

8. Types of Solar Design
3. Hybrid System
- Combination of Grid Tied and
Off Grid Systems.
- Generate power in the same way
as a common grid-tie solar
system but use special hybrid
inverters and batteries to store
energy for later use.
- Operate as a backup power
supply during a blackout.

9. Sample Computation
1. Grid – Tied System 1.5kWp
 Estimated Project Cost Php 124,000.00
 Applicable for establishments with electric bill of
P3000 to P4500 per month.
 A 1.5kWp system can power your refrigerator, TV,
a few fans, or a 1hp aircon during daytime.
 Projected Savings – P1,700 per month.

10. Sample Computation
2. Grid – Tied System 2.16kWp
 Estimated Project Cost Php 152,000.00
 Applicable for establishments with electric bill of
P4000 to P6500 per month.
 A 2.16kWp system can power your refrigerators,
TV, a few fans, lights, gadgets or 1.5hp aircon during
daytime.
 Projected Savings – P2,300 per month.

11. Sample Computation
3. Grid – Tied System 3.24kWp
 Estimated Project Cost Php 195,000.00
 Applicable for establishments with electric bill of
P6,000 to P10,000 per month.
 A 3.24kWp system can power your refrigerators,
TV, a few fans, gadgets or a 2hp aircon during
daytime.
 Projected Savings – P3,400 per month.

12. Sample Computation
4. Grid – Tied System 5kWp
 Estimated Project Cost Php 295,000.00
 Applicable for establishments with electric bill of
P9,500 to P15,000 per month.
 A 5kWp system can power your refrigerators, TV,
a few fans, gadgets or a 2 units of 1.5hp aircon
during daytime.
 Projected Savings – P5,700 per month.

13.  There is NO - one size fits all installation. Total project cost may vary depending on the
design, location, and cost of the system.
 Projected savings are based on Php 11.00 per kWh electricity rate.
 WARRANTY
10 years for PV Module
5 years for Inverter
2 years for workmanship
 Off Grid and Hybrid Computations are available upon request.
 Net Metering Application/Assistance (2nd Phase) – a different proposal with the client
after the solar installation.
Note:

14. Additional Services (2nd Phase after
Solar Installation)
Net Metering
- It is a utility billing mechanism
that offers a credit to residential
and business customers who are
making excess electricity with
their solar panel systems and
sending it back to the grid. It
allow customers to offset the
cost of power drawn from the
utility.
