Solar panels in Ecuador: three real quotes from $6,488 to $9,691 and how to compare them

The same system (12 panels, a 10 kWh battery and a hybrid inverter) in three quotes: $9,691 with installation and the CNEL procedure, or $6,488 and $6,826 for equipment only. What each includes and what to ask.

With the power cuts of recent years and ever higher electricity bills, many people are considering solar panels. This is what it costs, with three real quotes from September 2026 for the same system, what you can do yourself and what you can't.

A real case: three quotes for the same system

We asked for quotes for a house on the Manabí coast: 12 panels (about 7 kWp), a 10 kWh lithium battery and a hybrid inverter of 8 to 10 kW, to have power during cuts and save on the bill. The result:

• Quote A: installer, turnkey, $9,691.35. With installation, wiring and the two-way meter procedure with CNEL.
• Quote B: distributor, equipment only, $6,487.71. With an 8 kW inverter.
• Quote C: the same distributor, second version, $6,826.00. With a 10 kW inverter and more protection.

What quote A includes ($9,691.35)

• 12 Trina 625 W panels (7.5 kWp): $1,656 ($138 each), 25-year warranty.
• Deye 10 kW hybrid inverter: $2,926.50, 6-year warranty.
• 10 kWh lithium battery: $1,890, 6-year warranty.
• Protection and materials: $1,169. DC breakers, fuses and the battery breaker $168, aluminium mounting with clamps $345, 4 mm PV cable (60 m) $156, AC cable (100 m) $380, and AC breakers, breaker box and conduit $120.
• Installation: $1,250 (panels $650, inverter $600) and $380 for the two-way meter procedure with CNEL.
• The equipment carries 0% IVA (VAT); materials and services carry 15% ($419.85). The work is delivered in 10 days.

What quote B includes ($6,487.71)

• 12 Aiko 590 W panels (7.08 kWp): $1,668 ($139 each).
• Must 8 kW hybrid inverter: $2,278.
• Must LiFePO4 10 kWh battery: $1,830.
• Mounting (rails, clamps, L-feet, rail joiners): $419.36.
• A 125 A DC breaker ($41.52) and 100 m of solar cable ($158).
• 100% payment before dispatch; the quote is valid for 10 days.

What changed in quote C ($6,826)

• Must 10 kW inverter ($2,400) instead of 8 kW.
• New protection: a 250 A moulded-case DC breaker ($102), two 20 A DC breakers for the panels ($42), two surge protectors (SPDs, $70) and six pairs of MC4 connectors ($15.60).
• The solar cable now says 6 mm (100 m, $158).
• Everything else the same as B: panels, battery and mounting.

What comparing them taught us

1. "Equipment only" isn't the complete system. Between A and C there's a $2,865 difference, but C leaves out at least $2,130 of what A includes: installation ($1,250), the CNEL procedure ($380) and the AC side: cable, breakers, box and conduit ($500). Before comparing, add to the equipment-only quotes what they're missing.
2. Ask for the second version. C cost $338 more than B: the bigger inverter (about $122) and about $190 of protection the first version didn't have (plus IVA). The first quote looked cheaper, but it lacked surge protectors and breakers for the panels. Always ask what protection is included and have them write down the cable thickness.
3. The inverter and the battery are almost half the price. In A they add up to $4,816 of $9,691: almost 50%. The panels are only 17%. So the brand, warranty and size of those two parts matter more than the panels.
4. The warranty in writing, without contradictions. A says at the bottom "10 years on equipment, direct support and 3 months of monitoring", but the inverter and battery lines say 6 years: clarify which one applies. Quotes B and C don't mention a warranty; ask for it before paying.
5. Look at payment and deadlines. The distributor asks for 100% before dispatch and its quote is valid for 10 days; the installer accepts cash, transfer and card, and its quote is valid for 5 working days. With full payment up front, check who the company is.
6. An inverter bigger than the panels leaves room to grow. With 7 kWp of panels and a 10 kW inverter you can add panels later. Ask the installer how many it accepts.
7. What a 10 kWh battery gives you. Enough for a night with the essentials (fridge, lights, internet, TV, fans); not to run air conditioning for hours.

What an installed system costs

In quote A, with batteries, the complete system came to about $1,290 per kWp ($9,691 for 7.5 kWp). Without batteries, installers in Ecuador quote a turnkey grid-tied system at about $750 to $1,200 per kW: a 3 kW system then costs about $2,250 to $3,600.

What makes the price vary:

• Batteries: a grid-tied system without batteries is the cheapest; with lithium batteries you keep power during cuts, but the price goes up a lot (in A, $1,890 for the battery alone).
• Inverter: hybrid inverters (grid + batteries) cost more than grid-only ones.
• Mounting and roof: a flat concrete slab is simpler than a tiled or metal roof.
• Protection and wiring: breakers, earthing, surge protection.

Do-it-yourself kits

Online shops in Ecuador sell complete kits, for example a 5 kW hybrid kit for about $4,000, or a 5 kW kit with eight panels, an inverter and two lithium batteries for about $5,900. A kit is cheaper than an installed system, but keep in mind:

• Check the brand and warranty of the inverter and batteries: they are the parts that fail most.
• You need mounting suited to your roof and solar cable of the right thickness.
• A mistake on the DC side or with the batteries can cause a fire. Without electrical experience, have at least the connection done by an electrician.

Connecting to the grid: don't do it on your own

To feed power into the grid and save with a two-way meter, you need the procedure with your city's electricity company (for example CNEL) and, usually, a qualified installer who signs off the installation. In quote A that procedure cost $380. A system connected without approval can endanger the technicians who work on the grid and can bring penalties.

What makes sense?

• Only saving on the bill: a grid-tied system without batteries.
• Power during cuts: a hybrid system with batteries, or start with a smaller backup just for the essentials.
• An off-grid cabin: a stand-alone system, where a kit does make sense.

Look at your bill: the kWh per month you use say how many panels you need. Ask installers in your city for quotes on Build and read our article on power during cuts. Prices from real quotes of September 2026: always confirm with the installer.
