ENERGY THAT STARTS AT HOME10°18′ N · CEBU

Power for everyday livingPractical solar solutions for brighter, more comfortable homes.

We start with the appliances your household uses and when you use them. Solar production varies with sunlight, so the right system depends on your daily energy use, roof, and site conditions.

Talk through your household needs

Greater energy independenceUse sunlight to take greater control of household energy needs.

For many homes, a hybrid inverter can provide a path to compatible battery storage now or later. Backup depends on the selected equipment, battery capacity, and which circuits are connected for backup.

A cleaner energy futureSupport cleaner communities for a healthier, brighter Philippines.

Using power generated on-site can reduce how much electricity a home draws from the grid while solar is producing. The amount depends on the system, weather, and household use.

OUR VISION

Greater energy independence

A future where every Filipino household has the opportunity to take greater control of its energy, and communities thrive in homes powered by cleaner energy.

OUR MISSION

Responsible solar adoption

Help communities adopt solar through responsible installation and clear guidance, while contributing to efforts to reduce emissions and address climate change.

OUR COMMITMENT

Safety, care, and honesty

Help homeowners understand their system, its capabilities, and its limits—with practical recommendations for present needs and future plans.

02WHAT WE DO

Solar that fits
real life.

Residential projects are our current focus. For many homes, we recommend exploring a hybrid inverter that can work with solar now and support a compatible battery bank later. We’ll confirm the inverter, battery, and site before promising future expansion. Commercial projects need a separate scope review.

▰01 / 03

Hybrid inverter systems

Our residential-first option for many homes: start with solar, then add a compatible battery bank later if your needs change. We confirm battery support and system limits for the chosen model.

Grid-tied solar

For homes focused on using solar during the day without battery backup. We review the connection and site requirements before recommending this setup.

Site assessment

Review your electricity use, roof conditions, and equipment location before choosing a system.

A thoughtful first stepPrepare for a site assessment

System design and performance depend on actual usage, equipment compatibility, roof, and site conditions. Larger commercial projects require a separate assessment and scope review.

BATTERY BACKUP EXAMPLE

See how long a battery could support your loads.

Choose a sample 51.2 V battery bank, then enter the average load you want backed up. The estimate shows time until the battery reaches your selected reserve.

A planning example only. Actual runtime depends on the equipment, load changes, battery condition, inverter limits, and installation.

6 hours

After 6 hours at 600 W, estimated battery level is 75% SOC.

0% SOC20% reserve100% SOC

How this estimate is calculated

Nominal energy = 51.2 V × battery Ah ÷ 1,000. Usable AC energy = nominal energy × (starting SOC − reserve SOC) × 90% inverter efficiency. Runtime = usable AC energy ÷ average backed-up load.

SITE VISIT PREPARATION

FIELD NOTES

Solar notes, made useful.

Short, practical reads from our residential-first approach.

What to prepare for a site assessment

A recent electricity bill, your city or barangay, and a list of appliances you may add can help start the conversation. Roof photos taken safely from the ground are useful too. Our team still needs to inspect the roof, shading, electrical service, and equipment location before recommending a system.

Planning for a battery later

A hybrid inverter may offer a path to battery storage, but compatibility depends on the exact inverter and battery models. Before choosing, confirm supported batteries, power limits, backup circuits, and the space and wiring needed for a future installation.

What we review before sizing a home system

We look at your energy use, future appliances, roof condition, shade, electrical panel, and where equipment could be installed. These details help us compare practical system options instead of sizing from the bill alone.

04THE SIDLAK-PH WAY

A clear path
to your own power.

Select a step to see how Sidlak-ph guides your project—from the first review to handover.

01Understand your home and energy useWe start with your goals, electricity use, and the appliances you want solar to support.

Your monthly bill or kWh is a useful starting point. We also ask when you use power, whether backup matters, and what appliances you may add later. That helps us understand what you want the system to do before discussing equipment.

We’ll talk through

Your electricity bill or monthly kWh and location
Daytime use, backup needs, and future appliances
Your priorities and any questions about solar

Helpful to prepare

A recent electricity bill, if available
A list of appliances you want to support
Roof photos taken safely from the ground

02Assess the site and compare optionsWe check the property, explain our assumptions, and compare practical system choices.

We review roof condition and shade, electrical service, and possible equipment locations. Then we compare system sizes and battery options against the information available, explaining the assumptions, limits, and trade-offs in plain language.

During the review

Consider roof access, condition, shade, and layout
Review electrical panel, cable routes, and equipment space
Compare grid-tied or hybrid options for your needs

Before you decide

Review what equipment and installation work are included
Discuss system limits and backup circuits where applicable
Ask us to explain any line item or assumption

Final recommendations depend on an on-site assessment and the agreed project scope. Solar output and bill savings are not guaranteed.

03Install, check, and walk throughOnce the scope is agreed, we install the system and explain how it works at handover.

After you approve the project scope and schedule, our team carries out the installation. At handover, we review the equipment and controls with you so you know what your system can do and how to use it.

At handover, we’ll explain

Inverter and battery status, settings, and monitoring
Which circuits receive backup power, if included
System limits, safety devices, and who to contact

We’ll review together

How to check normal operation and monitoring
What to do if an alert or fault appears
Project documents and the agreed warranty terms

05YOUR FIRST STEP

Let’s start with
your situation.

Share a few basics and we’ll prepare a concise inquiry you can copy into your preferred messaging app.
