Optimus Energy introduction to solar in the Philippines.

ELECTRICITY IN THE

PHILIPPINES. • The Philippines has one of the highest costs of

energy in the world.

• Electricity prices have risen on average by 12.5%

per year over the last 20yrs.

• With economic growth expected to outstrip

increases in capacity, it is widely expected that

electricity prices will continue to rise sharply in the

short to medium term.

WHAT IS THE RISK FOR

INDUSTRY?

• Reduced competitiveness compared to other

manufacturing hubs in the ASEAN due to

electricity prices.

• Reduced output due to downtime derived

from increased black outs particularly in

summer months.

WHAT IS THE RISK FOR

HOMEOWNERS

• Continued exposure to increasing energy

prices creating increased pressure on

household budgets.

• Demand continually outstripping supply

creates a situation for more brown outs/

black outs.

OPTIONS!

• Reduce Energy Consumption.

• Reuse Energy Where Possible.

• Replace The Remainder With Solar.

WHY SOLAR?

• Solar Works During Peak Times.

• Solar Costs Less Than Other Alternatives.

• Photovoltaic Solar Is a Globally Proven

Technology.

HOW DOES SOLAR WORK?1. Solar Modules - convert energy from

the sun into DC electricity.

2. Inverter - an inverter turns DC

electricity into AC electricity.

3. Switchboard - the AC electricity

flows into the board & is used by the

property 1st.

4. Smart Meter - a smart meter is

installed to measure energy

consumed from the grid & energy

produced from solar.

5. The Grid - any surplus solar

electricity is fed back into the grid & is

sold.

HOW DOES OFF GRID

WORK?1. Solar Modules - convert energy from the sun into DC

electricity.

2. Regulator - A regulator or solar charge controller is

installed to stop the batteries over charging.

3. Control Board - The control board houses switching &

circuit protection devices.

4. Inverter - The inverter converts DC electricity into AC

electricity for use in homes & businesses.

5. Battery Bank - The battery bank is sized to suit the energy

demand within the application, usually with several days of

autonomy to cover for any cloudy days. these batteries can

be stored internally or externally.

6. Back Up Generator - A back up generator is installed as a

‘ just in case’ measure or for situations where demand out

strips available solar supply.

7. Wind Turbine - A wind turbine can also be installed to add

additional generation from renewable sources.

HOW DOES HYBRID

WORK?1. Solar Modules - convert energy from the

sun into DC electricity.

2. Inverter - an inverter turns DC electricity

into AC electricity.

3. Switchboard - the AC electricity flows into

the board & is used by the property 1st.

4. Smart Meter - a smart meter is installed to

measure energy consumed from the grid &

energy produced from solar.

5. The Grid - any surplus solar electricity is

fed back into the grid & is sold.

6. Batteries - Batteries are generally installed

on the DC side so that electricity can be

used during brownouts or when solar isn’t

available.

TYPES OF SOLAR

MODULES.• Monocrystalline - Traditionally

mono cells were more efficient than

poly, although this is less likely now

& are more expensive than Poly.

• Polycrystalline - Polycrystalline

cells are now the standard

throughout the world.

• Thin Film - Is great technology

specifically in shady conditions

although not cost efficient or space

efficient.

WHAT MAKES A CHEAP

MODULE?• EVA - The energy

required to bake EVA

onto the solar panel is

one of the most

expensive components. If

not baked correctly the

EVA quickly browns &

corrodes the cells/

connections causing

output degradation.

WHAT MAKES A GOOD

MODULE?

• Bloomberg Tier 1 rating.

• Linear warranty

• Positive Tolerance

BLOOMBERG TIER 1

Source: Bloomberg New Energy Finance

WHAT MAKES TIER 1?

• A company that manufactures it’s products under it’s own

brand.

• A company that has developed at least 5 multi megawatt

projects in the previous quarter.

• These multi megawatt projects must of been funded by at

least 5 independent banks (non development).

• The company must have not entered into any bankruptcy

proceedings.

LINEAR WARRANTY

• All solar modules degrade.

• Generally 3% year 1.

• Then by a smaller amount each

year.

• After 25yrs a good module will

still be 80% as good as day 1.

• A linear warranty will guarantee

a small amount per year.

POSITIVE TOLERANCE

• No module is generally exactly it’s rated

power.

• Standard modules have a +/- tolerance

meaning that you might get 253w or 247w

(from a 250w)

• A good module will always be + only. 250-

253w

INVERTER TYPES

• String Inverters

• Hybrid Inverters

• Micro Inverters

STRING INVERTER• Standard Inverter

Type.

• Available in 1-5kW

single phase.

• 5-20kW 3 phase.

• Can add multiple

inverters.

HYBRID INVERTER

• Smarter inverter

• For use with batteries

• Available in 3.6kW-

5kW single phase

configurations.

MICRO INVERTER

• Latest technology

• More versatile than string

inverters

• Higher yield in most

installations.

• Higher cost than string

inverters.

SOLAR RACKING OPTIONS

• Tin Roof

• Tile Roof

• Flat Roof
