Multan · Older houses

Cantt and Gulgasht solar in Multan: shade and the bill come before the plate count.

پرانے گھروں میں چھائیں اور بل کی حد پلیٹوں سے پہلے آتی ہے۔ گیسر گرڈ پر رہتا ہے۔

These houses already have one or two splits, a water tank on the south, and a feeder that was sized years ago. Count usable bays after shade. Then read the sanctioned load on the bill. A 15 kW conversation does not belong here.

Keep the geyser on GRID. A backup board that includes the geyser is how a small pack dies at night. The DB split is in backup DB design.

Shade on Cantt, Gulgasht, and Officers Colony roofs before any plate count

Cantt, Gulgasht, and Officers Colony are older Multan houses. The slab is usually reinforced concrete. One or two splits are already installed. A water tank sits toward the south, a mature tree stands in the lawn, and the parapet is often high enough to cut the winter sun. The satellite picture still shows a tidy rectangle. That rectangle is not the array. We draw the shade the tank, the tree, and a neighbour's upper floor actually throw, then we count bays only in what remains. Ordering a full row of ten 645 W N-type modules for a roof that keeps a handful of clear bays in the afternoon is how a string spends half the day doing little. The plate count comes after the drawing. A 15 kW opening line does not belong here.

Send a morning photograph and an afternoon photograph with the tank in both, plus a view along the parapet. If the tree's shadow crosses the south bays, those bays are not a string. The drawing method lives on the shade page. This URL adds the local habit: these three neighbourhoods lose area to tanks and trees more often than a new society plot does. A generic line that every Gulgasht house gets a fixed plate count, with no shade plan, is a sentence we will not sign. Fewer 645 W modules on clear bays beat a crowded layout that only looks complete from the lane. If the clear area is tiny, the honest sale is the fan product, and the hybrid badge waits.

Usable bays on an old Multan slab, not the photograph

A bay is a place a module can sit for the hours that matter, on iron that can carry a plate in the 640 to 650 W class. If the only clear strip is to one side of the tank, the string is laid for that strip or the job shrinks. Shade mixed along one string pulls the whole string down with the weakest module. On these roofs the honest answer is a shorter string, not a clever mix of leftover wattages beside the tank. The open bays get one module family. The shaded bays stay empty. We do not fill a gap with a different plate so the roof looks finished from the street.

Iron, when we do mount, is 14 SWG. Sixteen SWG under a module in the 640 to 650 W class is refused, including where someone calls the span short because the parapet is low. PVC as the roof cable protection is refused in this heat. XLPO is the cable we sign, and it does not lie in a water channel behind the tank. The usual inverter is a 6 kW IP65 hybrid on a shaded wall with air around it. The pack lives indoors. None of that iron talk moves the plate count ahead of the shade drawing. The house hybrid page is the national box. This page is why many of these roofs never reach a full ten-module layout.

The sanctioned load on a Cantt bill comes before a bigger inverter

These feeders were sized years ago. The family has since added machines the original sanction did not imagine. The sanctioned load printed on the MEPCO bill is the ceiling of the connection, and a shop quotation does not raise it. If that figure is smaller than the inverter someone wants to hang, the increase is a MEPCO paper and it is filed before the bigger box is ordered. We do not quote a DISCO fee, and we do not invent an office phone. The national note is sanctioned load. The local file note is the Multan MEPCO file. New Pakistani files after 9 February 2026 are net-billing under SRO 251(I)/2026. Net-billing is the shape of a new file. It is not a reason to skip the sanctioned-load line, and it is not a rupee figure this page will print.

Read the bill beside the night sheet. Fans, a fridge, and lights can often stay inside a modest sanctioned load and a 6 kW hybrid. Two night air-conditioners are a different service, and the bill has to be able to say so before anyone talks about an 8 or 10 kW box. The day load and the service both have to support that move. Shade still has a vote. A large inverter on broken bays is an idle badge. Output priority on the circuits that are meant to run stays solar-first. That choice is not a way to put the geyser on the pack.

A load increase is paper, not a sticker

A load increase is not a verbal promise from a counter, and it is not a badge on the hybrid. Until the DISCO paper exists, we size to the bill in hand. The carton and the bill beat the website. If a forwarded quote shows a bigger inverter than the sanctioned load, bring the bill before you pay. The calculator working rate of Rs 11 per kWh is only a labelled working rate. It is not the MEPCO tariff and it is not a fee. September 2026 street bands live on the prices page. No band figure is copied onto this Cantt page. Officers Colony, Cantt, and Gulgasht do not get three tariffs from us. They get the same order of work because the roofs fail the same way.

The Multan city page remains the city canonical. Use it for the desk, the circle, and the introduction. Use this URL when the question is whether this old roof, under these trees, on this bill, should carry plates. Phone and WhatsApp for that question are 0300 0465810. Email is info@zarkaarpower.com. These pages were updated on 2 October 2026. Malik Muneeb Altaf is group steward only, not an installer licence, and that name does not approve a cantonment drawing. Zarkaar Power is the solar desk of Zarkaar Group (Pvt.) Ltd. in Multan. This page does not promise a drive-out. It asks for the bill and the roof photographs.

Night intention in Officers Colony before the hybrid badge

Write the night before the badge. Four fans are about 300 W. A fridge cycles. Ordinary lights are a small addition. That set is one 5.12 kWh-class pack, and a 6 kW IP65 hybrid is the usual ceiling on these roofs rather than a mean default. One 1.5-ton for part of the night is a second pack. The one AC guide and the fans or one AC page hold that arithmetic so this neighbourhood does not invent a second climate story. Two night air-conditioners are three or more packs, and only after the hours are written. We will not hide those hours inside a larger inverter sticker while the roof is still broken by shade.

A backup board that includes the geyser is how a small pack dies after dark. The element does not know the family only wanted air in the bedrooms. Keep it on GRID. The split is drawn on the backup DB design page. Solar-first remains the output priority for the circuits on the backup side. If the night sheet is only fans, do not let a showroom add a second pack because the lane looks established. Idle lithium is not a design. If the night truly needs the tonne, say so, price the second pack, and still leave the geyser off that bus. A 51.2 V wall does not go on a 24 V inverter left over from an older house, and USE on a battery-type screen is a walk-away. Four tubulars are not the 2026 hybrid bank.

Old Cantt wiring and the trip we will not hide

These houses were wired for a quieter life. A new backup distribution board on that cable can trip the residual-current device in the first week, especially where a damp joint or a tired socket is already leaking. The photograph of the tripped device is the start of the repair. The fault note is RCD trips. We do not lift the earth to keep the lights on, and we do not bridge the device so a handover looks clean. Leakage is the fault. Repairing it is slower than hiding it, and it is the only work we will sign. If you smell smoke or burning insulation, isolate only if that is safe, leave, and call local emergency services. This page does not teach a way to keep running through that smell.

We also do not invent an earth-resistance number for Gulgasht. A real reading belongs on the handover when an electrician has taken it. We do not publish a test procedure. You keep the photograph of the board and of the device that opened. The same refusal covers a shop LCD that shows USE, and a set of four tubulars offered as the lithium bank. Closed loop, on the pack that was actually sold, is the quote. The cantonment or the society, where one of them owns the permission, signs its own drawing. We size the plant. We do not pretend a solar quotation is that signature, and we do not publish a fake colony form.

This Cantt and Gulgasht URL stops at shade, the bill, and 6 kW

Some roofs in this belt need a written yes from an office that is not ours before anyone drills. Bring that answer with the bill. A person who cannot get the owner to agree does not get a drill. No file and no willing owner means feed-in stays off. None of those papers change the order of the engineering. Shade first. Sanctioned load second. Night sheet third. Plates last.

The decision on this Cantt, Gulgasht, and Officers Colony URL is to draw the shade and read the sanctioned load before any plate count, to keep the geyser on the grid breaker, and to treat a 6 kW hybrid as the usual ceiling unless the clear bays, the MEPCO bill, and a written night sheet all agree to move. That decision is false for a clean new roof on Bosan Road, false for a Vehari Road mill, and false for a bazaar board swap. The Multan city page stays the city canonical. This page is only the older roof.
