Practical articles for installers and engineers, technology explainers and profiles of the manufacturers whose equipment is sold in Brazil.
Batteries are no longer just for off-grid. With Fio B rising and lithium prices falling, storage is starting to make sense in Brazil — the cases where it already pays to recommend it.
The opening of the free market widens the game beyond distributed generation. The difference between ACL and DG and how installers can position themselves to profit.
The "end of the exemption" scared the market, but solar still pays off well. The Fio B transition under Law 14,300, the year-by-year percentages and how to explain it without losing the sale.
Confusing Group A with Group B leads to wrong proposals and frustrated customers. Voltage, tariff, demand and modalities — and why they change the whole sizing.
Each rejection in the access opinion postpones the installation and wears down the customer. The errors that most often sink projects at the utility — documents, protection and data — and how to avoid them.
Installing more module power than the inverter's rating increases generation — up to a point. How to calculate the DC/AC ratio, what the safe range is and when clipping stops being your friend.
Talking about IRR and NPV scares customers away. Simple analogies and a conversation script to explain the return on a solar investment and turn doubt into a decision.
"I found it cheaper elsewhere." Instead of giving a discount, show what the customer does not see in the competing proposal: after-sales, honoured warranty and O&M.
From the electricity bill to the number of modules and the inverter: the complete step-by-step process to size a photovoltaic system without mistakes and with real savings for the customer.
A system sale is one-off revenue; O&M is revenue every month. How to structure operation and maintenance plans, what to include and how to price them.
A module torn off by the wind means lawsuits and losses. Wind loads under NBR 6123, suction at roof edges, anchoring and ballast to design safe structures.
PID and hot spots eat into generation and can even cause fires. What they are, why they happen and how to detect them with thermography and monitoring before the damage.
In Group A, the customer pays for demand and consumption separately — and solar does not reduce demand. How to size industrial and commercial projects without promising what solar cannot deliver.
Without monitoring, you only find out about a fault when the customer complains about a high bill. What to track, which alerts are gold and how to call before the problem.
Irrigation, dryers, milk cooling: farms consume a lot and have their own credit lines. How to approach farmers in the right language and close large projects.
Most customers do not have the cash up front — and that is fine. The credit lines for solar energy in Brazil and the argument that closes: an instalment smaller than the bill savings.
The installation is finished, but without approval the customer offsets nothing. The complete process — access request, access opinion, inspection and meter — and the deadlines to keep it moving.
Dust, soot and bird droppings silently eat into generation. When to recommend cleaning, how often and how to turn a simple task into recurring revenue.
Is your proposal becoming a price list the customer uses to negotiate with your competitor? The five elements that turn a quote into a proposal that closes the deal.
String, microinverter or optimizer? The wrong choice costs generation and money. In which scenarios each architecture wins — shading, complex roofs, safety and budget.
Both generate electricity from sunlight, but cutting the cells in half changes efficiency, shading tolerance and durability. A direct comparison of the two module designs.
Two active faces: the front captures direct sunlight and the rear uses light reflected by the ground. Up to 30% more energy where the albedo is high — and less gain on an ordinary roof.
Simple payback ignores the time value of money; discounted payback does not. The inputs, the formulas, a worked example and the common mistakes that make a projection too optimistic.
A single silicon crystal or many fused crystals: the difference shows up in efficiency, area per kWp, appearance and price. Why monocrystalline now dominates the market.
Boron-doped P-type cells were the standard for decades; phosphorus-doped N-type cells (TOPCon, HJT, IBC) are more efficient and degrade less. Where the market is heading.
Three ways to convert and optimise the energy of a solar array, each with its own cost, shading behaviour and monitoring. When each one is the right choice.
An algorithm inside inverters and charge controllers that keeps the panels working at their point of maximum power, minute by minute, as light and temperature change.
