System Types

GRID TIE SYSTEM

A grid-tie system works together with a utility power grid (i.e. Meralco). During the day, the solar panels generate electricity and during the night (or when solar power is insufficient), power is drawn from the grid.

Best for customers looking for the most cost-effective option for solar and doesn’t need a battery storage.

HYBRID SYSTEM

System that uses solar during the day while also charging battery for both night-time and emergency use.

Best for customers who need uninterrupted power.

OFF GRID SYSTEM

System that uses Solar during the day while also charging battery for both night-time and emergency use.

Bests for customers whose property is located in remote areas.

Net-Metering

This is how Zarcilla Solar Systems work:

SOLAR PANELS produce DC electricity out of sunlight – even without direct sunrays hitting the solar panels!

The INVERTER converts the produced DC electricity into consumable AC electricity.

SOLAR ENERGY gets automatically supplied to all of your APPLIANCES. If you need more electricity than solar panels produce, it gets supplied by the UTILITY as usual.

Excess solar electricity is automatically sold to your UTILITY, lowering your electric bill even further. This process is called Net-Metering.

Solar Panel Installation Cost

Factors That Affect the Cost of Solar Panel Installation

The cost of solar panel installation can vary widely based on several factors. Here’s a breakdown of the key elements that influence the overall cost:

Panel Size: Larger systems with more panels will naturally cost more. The more electricity you want to generate, the larger the system you’ll need.
Energy Needs: Higher energy demands require more panels or higher-efficiency ones, increasing the cost.

Monocrystalline vs. Polycrystalline: Monocrystalline panels are more efficient but also more expensive compared to polycrystalline panels.

Roof Type and Condition: Roof material, pitch, and structural integrity affect labor costs. Complex roofs with multiple angles may require more time and effort, increasing costs.
Ground-Mounted Systems: If not installing on a roof, ground-mounted systems often require additional materials and labor, adding to the overall cost.

Labor costs vary based on location, local solar installers, and the complexity of the installation. Highly skilled labor for customized installations will be more expensive.

String Inverters: These are less expensive but may not perform well in areas with shading issues.
Microinverters: More expensive but better at optimizing performance when shading or uneven energy production occurs.
Hybrid Inverters: Functionality with battery storage, allowing for efficient energy management, backup power during outages, and optimal use of solar energy.

Mounting Hardware: The cost of brackets, rails, and mounting materials adds to the total.
Wiring and Electrical Components: Wires, conduits, and other electrical materials also contribute to the cost.
Battery Storage: Adding solar batteries to store excess energy significantly increases costs but offers more energy independence.

Local building permits, inspection fees, and utility interconnection fees can add several hundred to a few thousand dollars, depending on your location.

The amount of sunlight your region receives affects energy production. Areas with less sunlight may require larger systems to meet energy needs, raising the overall cost.
Installation costs and local regulations can vary based on location.

Outright Purchase: Paying in full upfront may be more expensive initially but can lead to long-term savings.
Installment via Credit Card

Some systems come with long-term warranties that could affect the initial purchase price. You might also need to factor in potential maintenance costs, although solar systems are generally low-maintenance.
