Standalone Solar with Storage

Off-Grid Solar with Battery Storage

Solar makes the power. Batteries hold it for the evening and the night. No grid connection needed.

An off-grid system is built for a place the grid does not reach, or reaches so unreliably that it cannot be depended on. Paso Solar assesses your daily load, sizes the panels and battery for it, and builds in a plan for the odd stretch of bad weather.

What off-grid solar replaces

Off-grid is usually not compared against a normal electricity bill. It is compared against what you would otherwise spend to get power to the site at all.

No grid extension cost

Bringing a line to a distant plot can mean paying for poles, cable, and a transformer. An off-grid system avoids that one-time cost entirely.

No diesel bill

Where a generator runs today, every hour costs fuel and servicing. Solar and batteries take over the routine load and the generator becomes a rare backup.

No monthly demand or fixed charges

With no connection, there is no meter, no minimum bill, and no tariff revision to absorb each year.

A known cost, once

After the system is paid for, the running cost is panel cleaning, periodic checks, and eventually a battery replacement, which we tell you about upfront.

The one recurring cost to plan for is battery replacement over the life of the system. We put that in the proposal so there are no surprises later.

How an off-grid system works

The battery is the heart of it. Everything is sized around what you use in a day.

During the day

The panels run whatever is switched on and put the rest into the battery. On a good day the battery is full by afternoon.

In the evening and at night

The property runs entirely off the battery. There is no grid to fall back on, so the battery has to be sized for the full overnight load.

On a run of cloudy days

Generation drops. The design covers this with spare battery capacity, a backup generator, or a plan to run only essential loads until the sun is back.

Load discipline matters

An off-grid system has a fixed daily budget of power. Big unplanned loads have to be managed, which is why the load assessment at the start is so important.

What is in an off-grid system

More parts than an on-grid system, because the storage and the safety around it have to be built in.

Solar panels and mounting

Sized to refill the battery and carry the daytime load, on a ground frame or roof structure rated for local wind.

Charge controller

An MPPT controller that gets the most out of the panels and protects the battery from over- and under-charging.

Battery bank

Lithium or, in some cases, lead-acid, sized to your overnight load and the backup margin you choose.

Off-grid inverter

Produces a clean, stable AC supply for your appliances and manages the switch between solar and battery.

Backup and protection

Generator changeover where needed, plus isolation, surge protection, and earthing.

What we work out first

Your daily units
Every regular load added up, hour by hour, to get the units you use in a day.
The overnight share
How much of that runs after sunset, which sets the battery size.
Backup margin
How many low-sun days you want to ride out before the generator or essential-load mode comes in.
Peak and surge loads
Pump starts, motors, and anything that draws a big spike, which sets the inverter size.

Honest about the trade-off

Off-grid buys you independence, but a battery large enough to never run short in any weather is expensive. Most good off-grid designs strike a balance: enough storage for normal life, and a backup for the rare bad week. We will show you where that line sits for your site and budget.

Where off-grid solar fits best

Off-grid earns its place where there is no practical grid connection, or where the supply cannot be trusted.

Sites with no grid

Land, estates, and buildings where the nearest line is far and a connection is expensive.

Farmhouses and estates

Lighting, pumps for domestic use, fans, and refrigeration away from a reliable line.

Areas with long outages

Places where the supply exists but fails often enough that a generator already runs.

Standalone equipment

Telecom sites, monitoring stations, and small installations that must stay powered on their own.

If you have a reliable grid connection and only want backup during outages, a hybrid system is usually the better and cheaper choice.

On-grid, hybrid, or off-grid?

The right choice comes down to whether you have a grid connection and how much independence you need.

Off-grid solar questions

How many days of backup does an off-grid system give?

That is a design choice. More battery means more cover on a run of cloudy days, but also more cost. We usually design for the load you cannot do without, plus a margin, and keep a generator or a smaller essential-load plan for a long overcast spell.

Can an off-grid system run my whole property?

It can, if it is sized for it. Off-grid works best when the daily load is known and fairly steady. Very large or spiky loads such as welding, borewell starting surges, or several air-conditioners together push the battery and inverter size up quickly, so we plan those carefully.

What happens when the batteries run low?

The system protects the batteries by cutting supply before they are fully drained. To avoid that on a bad-weather stretch, an off-grid design normally includes either extra battery capacity, a backup generator, or a plan to run only essential loads until the sun returns.

How long do the batteries last?

It depends on the battery type and how hard they are cycled. Lithium batteries used in solar typically carry a warranty in the range of 5 to 10 years. The batteries are the part of an off-grid system that will need replacing during its life, and we tell you that cost upfront.

Is off-grid cheaper than getting a grid connection?

Sometimes. Where the nearest line is far away and the connection and pole cost is high, or where the supply exists but fails often enough that you already run a generator, off-grid can work out better over time. We compare both for your site rather than assume.

Do you provide off-grid systems for farms and borewell pumps?

Yes. A borewell pump on a farm is usually handled as a dedicated solar pump system. Farmhouse lighting, a dairy, or a poultry shed is handled as an off-grid or hybrid system. We can design them together.

What upkeep does an off-grid system need?

Panel cleaning, a periodic check of the charge controller and inverter, and keeping the battery area clean, dry, and ventilated. Lithium batteries need very little attention; lead-acid types need their terminals and, in some types, water levels checked.
