Solar energy
A five-figure investment attached to a property. It starts with your electricity bill and ends with the meter changed.
Sollar Sul · Florianópolis — Brazil
Solar and electrical work, with the paperwork done
The hard part of a photovoltaic system is not the panel — it is the ART, NBR 5410 and the CELESC grid connection. That is what this site is about.
Choose your path
These are two businesses, and you came for one of them
Someone with a burning smell in the distribution board and someone sizing a photovoltaic system have nothing in common except the contractor. One is an emergency, the other is a planned investment — which is why the site splits here, on the first screen.
Electrical installation
Electrical installation
Distribution board, earthing, service entrance, fault-finding. Often urgent, which is why the phone comes before the form.
Solar
What goes into a photovoltaic system
No system size, no price and no brand. None of the three has been verified, and none appears here until the business supplies it.
Feasibility assessment
Roof orientation, shading, available area and your actual consumption read off the CELESC bill — not a rule of thumb.
Design and sizing
The system is sized against your consumption history. No system size appears on this site without that history in hand.
On-grid installation
Mounting, DC and AC wiring, string configuration and protections, with the electrical side executed to NBR 5410.
CELESC grid connection
The access request and approval process with the utility. Who carries that process — us or you — is the most important question in this quote. [CONFIRM who carries it]
Off-grid, hybrid and storage
Whether they do any battery work at all [CONFIRM] — nothing has been assumed here.
Monitoring and maintenance
Cleaning, inverter monitoring and periodic inspection. Frequency and scope [CONFIRM].
How grid connection works
From "I want solar" to the meter changed
This is the block that does not exist on any solar site in Floripa, and it is exactly what every buyer is anxious about. Five stages, in plain language, saying who does each one.

Bill analysis and feasibility
We read your consumption history off the CELESC bill and look at the roof, its orientation and shading. This is where you find out whether the project makes sense at all.

Design and the ART issued by the responsible engineer
The design is signed by a CREA-registered professional, who issues the ART — the formal record of technical responsibility (Lei 6.496/1977). [CONFIRM who the responsible engineer is]
Sollar Sul -
Access request to CELESC
The access request and the utility opinion, under the distributed-generation rules consolidated by Lei 14.300/2022. [CONFIRM whether Sollar Sul carries this process]
CELESC -
Installation
Mounting, cabling, inverter and protections. The electrical side follows NBR 5410.
Sollar Sul -
Inspection and meter change
The utility inspects and swaps the meter for a bidirectional one. From that point the system is connected and approved.
CELESC
How long does it take? No typical timeline appears here because none has been confirmed [CONFIRM the typical timeline] — and because part of it is utility processing time, which is outside any installer control. Saying so is more honest than promising weeks.

Electrical
What goes into an electrical installation
Executed to NBR 5410, the Brazilian standard for low-voltage electrical installations — naming the standard is a credential, not jargon.
Residential electrical installation
New build and full rewire, executed to NBR 5410.
Distribution board, breakers, RCD and SPD
Bringing the distribution board up to standard with a residual-current device and surge protection — and surge protection is genuinely relevant on this island.
Earthing and lightning protection
Earthing, and lightning protection under NBR 5419 — which is a separate discipline. [CONFIRM whether they do SPDA]
CELESC service entrance
Meter box installation and compliance with the utility standard.
Inspection and report
Inspection, thermography and fault-finding. Report scope [CONFIRM].
EV charger installation
The obvious neighbour to solar, and the easiest question to ask someone who has just had panels fitted. [CONFIRM whether they do this]
Emergency callouts [CONFIRM whether they offer them and on what hours] — nothing has been assumed here, and if they do, the phone moves to the top of this page.
Safety and compliance
Why you should demand an ART from your installer
This is not a legal disclaimer — it is the strongest sales argument this business has, because a good deal of the competition issues no ART at all.
NBR 5410
The Brazilian standard for low-voltage electrical installations. It is what separates an installation that is properly done from one that merely works.
ART
The formal record of technical responsibility, issued by a CREA-registered professional (Lei 6.496/1977). It is the document that says who is technically answerable for the work.
CREA-SC
The responsible engineer registration. [CONFIRM the registration and the name] — no number has been invented in this mockup.
What happens without an ART
An installation with no ART can become a problem with insurance and on resale, because there is nobody formally responsible for it.
If Sollar Sul neither holds nor contracts a CREA-SC registration, this entire section has to be rewritten and the site must not imply technical responsibility the business does not have. It is the first thing to resolve. [CONFIRM]

Installed work
Captions by type and neighbourhood. No caption carries a kWp or a generation figure, because none has been documented — and a generation number in a caption is a performance claim.
Request your quote
The number that changes everything is on your electricity bill
Solar is the one service on this site where a form beats WhatsApp, because the quote needs structured input. The field that matters is average consumption in kWh.
A prior written estimate itemising labour, materials and dates (CDC art. 40), binding for 10 days from receipt unless otherwise agreed — and nothing outside it can be charged without authorisation.
What about uploading the bill? An electricity bill carries a name, an address, an installation number and a consumption pattern — personal data with real weight. So this mockup does not implement an upload: the safer path is to send a photo on WhatsApp, and if an upload really is wanted it needs a stated purpose, a retention period and a deletion route in the policy. [CONFIRM whether they want the upload]
Would rather send a photo of the bill? Send it on WhatsApp.

Warranty
There are three separate warranties
Legal warranty — 90 days
Durable goods and services carry a 90-day statutory warranty from delivery (CDC art. 26, II). It applies whether it is written down or not.
Installation warranty
Any longer period is contractual and must be given in writing (CDC art. 50). [CONFIRM the terms]
Manufacturer warranty
Panel and inverter each carry their own warranty, typically long and heavily conditioned. Neither has been described here, because neither has been read. [CONFIRM both]
If any financing or instalment option is offered, it must show the cash price, the total instalment price, the number and value of instalments and the interest rate (CDC art. 52 and Decreto 5.903/2006). Naming a bank or a credit line needs the partner permission. [CONFIRM]
FAQ
What people ask before signing
How long does grid connection take?
It depends on two things: what sits with the installer and what sits with the utility. Nobody who installs panels controls the second part. Typical timeframe [CONFIRM] — no number has been estimated here.
Who issues the ART?
A professional registered with CREA, who takes on technical responsibility for the work (Lei 6.496/1977). Who that professional is at Sollar Sul [CONFIRM].
Does CELESC have to be notified?
Yes — a grid-tied system requires an access request and utility approval. Who files it, the installer or you, is the question to ask before signing [CONFIRM].
What happens to surplus energy?
Surplus enters the distributed-generation compensation scheme, whose legal framework is Lei 14.300/2022. The rules changed and carry a transition regime, so this site publishes no promise of compensation, tariff or acquired right without a dated source [CONFIRM with source and date].
Does it work in a blackout?
On an ordinary grid-tied system, no. When the grid drops the inverter shuts down for safety — including to protect line workers. Only a battery and a suitable inverter keep a load running. That is the honest answer, and hardly anyone gives it before the sale.
Do panels need cleaning?
Yes, periodically — dust, sea air and leaves cut output. Frequency and whether it falls under a maintenance contract [CONFIRM].
What is the warranty?
There are three and they are not the same thing: a 90-day statutory warranty (CDC art. 26, II), a written contractual warranty on the installation (art. 50), and the factory warranties on panel and inverter, which are separate and carry their own conditions. [CONFIRM all three]
Do you take electrical emergencies?
[CONFIRM whether they do and during what hours] — nothing has been assumed.
How much will I save?
This site publishes no savings percentage and no payback period, deliberately: those numbers depend on your tariff, your consumption, the pitch and shading of your roof and the compensation rules in force. Send your bill and the conversation starts from real data instead of a brochure figure.
