The full list of serviced suburbs and towns is on the Locations page, so check there if your area is not shown on the homepage.

Savings vary with usage, but a 5-kilowatt system in south-east Queensland typically saves a household between $1,200 and $1,500 a year, based on AHLEC Solar’s customer data. AHLEC Solar can provide a free personalised report showing your estimated savings, payback period and return on investment for your specific property and solar system size.

Yes, AHLEC Solar offers a free, no-obligation consultation and quote for every solar enquiry. A team member will assess your energy usage, roof space and budget, then recommend an on-grid, off-grid or hybrid solar system sized correctly for your Sunshine Coast home or business before you commit to anything.

Small solar panel setups for boats and caravans can be self-installed, but household systems require an accredited electrician. Connecting a full household or business system to the grid must meet Queensland’s electrical safety and grid-connection standards, which only a licensed installer can certify.

Solar panel installation cost depends on system size, typically starting around $6,995 for a mid-size 5-kilowatt system. Prices range up to $11,695 for that size after the STC rebate, and larger systems or premium brands cost more – AHLEC Solar recommends a free quote for accurate pricing.

The number of solar panels a house needs depends on how much electricity the household uses. Most AHLEC Solar customers are satisfied with a 6-kilowatt system made up of around 20 panels rated at 300 watts each.

Solar panels connect to a home through the switchboard, wired in by a licensed electrician. AHLEC Solar’s fully trained electricians handle this connection as part of every installation.

Making your own solar panels is technically possible but extremely time and labour intensive, with unpredictable power output. AHLEC Solar recommends buying panels from established tier-1 manufacturers rather than attempting a DIY build.

Most tier-1 manufacturers make excellent solar panels, and AHLEC Solar stocks trusted brands including Jinko, Longi, REC, Hyundai and Qcells. For warranty strength specifically, Sunpower and LG remain among the strongest performers in the industry, though tier-1 brands generally offer comparable 25-year performance warranties on panels.

No permit is required to install residential solar panels in most cases; only approval from your electricity distributor is needed. AHLEC Solar handles this distributor approval as part of every installation project.

Installing your own solar panels is not recommended unless you hold the right electrical training and qualifications. Some companies sell mounting systems for DIY installers, but AHLEC Solar advises using a licensed electrician for the wiring and grid connection.

Monocrystalline panels are the most efficient solar panel type, producing more output per square metre than polycrystalline. Systems larger than 5 kilowatts see little annual output difference between monocrystalline and polycrystalline, so either option can work well at that scale.

Solar panels add modest value to a property mainly by attracting buyers rather than significantly raising sale price, since installation costs have fallen in recent years. A home with panels is more likely to sell first than a comparable home without them.

Solar panels can technically overheat, but this is very unlikely in normal conditions. Most solar cells have an upper operating temperature of around 85C before performance is affected.

Solar panels do not make houses hotter and can actually shield the roof from direct sun. Panels installed with at least 100mm of clearance above the roof allow cooling airflow underneath, keeping the roof cooler.

Solar panels can work in indirect sunlight, though they perform best in direct sunlight where the maximum number of photons reaches the cells. Indirect or diffused light still produces usable, if reduced, output.

Solar panels do get hot to the touch, especially the anodised aluminium framework in direct sun. AHLEC Solar recommends scheduling panel maintenance for early morning or evening to avoid the heat.

Yes, solar panels genuinely save money on power bills, though savings vary with usage and rates. A 5-kilowatt system in south-east Queensland typically saves a household between $1,200 and $1,500 a year, based on AHLEC Solar’s customer data.

Cost depends on the system size and how much usable roof space faces the optimum direction. For a typical 5-kilowatt system suited to a 1,500-square-foot home, expect to pay between $6,995 and $11,695 after the STC rebate, though AHLEC Solar recommends a free on-site assessment for an accurate cost.

The most powerful solar panels sold commercially reach roughly 22% efficiency, though lab-developed cells have hit 44.5% efficiency in research settings. Higher-efficiency cells generally cost more to manufacture, which is reflected in the panel’s retail price.

The three main types of solar panels are monocrystalline, polycrystalline and thin-film. Thin-film panels are used far less today because they are less efficient and need more roof area to generate a comparable amount of power.

Yes, solar panels wear down slowly over time, losing up to 2% of capacity in the first year and about 0.5% each year after that. Manufacturers back this gradual wear with a 25-year performance warranty guaranteeing at least 80% minimum output.

No, solar panels are not finished after 25 years – they keep producing power but at a reduced output. Most panels carry a 25-year performance warranty guaranteeing at least 80% output, and AHLEC Solar has seen well-maintained systems keep generating usable power well beyond that milestone in Queensland conditions.

Solar panels do not work at night because they need photons from sunlight to generate power. Moonlight reflects far too few photons to produce any meaningful output, even during a full moon.

Monocrystalline panels generally outperform polycrystalline panels in smaller systems, since polycrystalline needs more panels to reach the same output. Above 5 kilowatts the difference narrows, so either panel type performs similarly at that system size.

Solar energy has very few disadvantages, mainly the upfront cost and roof space needed. Aesthetics can be a minor concern for some homeowners, but AHLEC Solar’s low-profile panels and long-term savings on electricity bills outweigh the initial investment.

Yes, solar panels still work when it’s cloudy, though cloud cover can cut incoming sunlight by up to 90%. Output falls by roughly the same proportion as the sunlight blocked by the clouds.

Solar panels stop generating power when there is no sunlight at all, such as after dark. They continue working on cloudy days, but output drops to a fraction of a sunny day’s performance.

Solar water heaters do not work at night since they need sunlight to operate. Most units stay connected to the grid, so households still get hot water after dark by drawing on grid power.

Solar panels do not need direct sunlight to work, though output is noticeably higher in direct sunlight than in diffused or indirect light. Panels will still generate some power on overcast days.

Solar panels do work on rainy days, though the accompanying cloud cover reduces output. Rain also helps wash dust off the panel surface, offering a small maintenance benefit.

Solar panels cannot use moonlight to generate meaningful power because moonlight carries far too few photons. Moonlight is simply reflected sunlight, so it is much weaker and more diffuse than direct sunlight.

Partially shaded solar panels still work, though their output drops while shaded. Many panels include bypass diodes that redirect current from brighter sections around the shaded cells, but panels in total shade will not generate power.

Solar panels need light, not heat, to generate power, and are tested at a standard 25C to measure efficiency. Above 25C, panel efficiency drops by around 4% for every 10C increase in temperature.

Solar water heaters still work on cloudy days, but output drops significantly compared to sunny conditions. After several cloudy days in a row, households may draw some grid power to keep water hot.

Solar panels should be cleaned the same way as any glass surface, using a soft cloth or sponge with soapy water. Abrasive materials should be avoided since they can dull the glass layer covering the cells.

Solar panels themselves do not damage a roof, though poor installation work can cause damage if handled incorrectly. AHLEC Solar uses accredited, experienced installers specifically to avoid this risk.

A gentle pressure washer can be used on solar panels, but high-pressure blasting should be avoided. Panels can withstand hard rain, so a garden hose is generally the safest cleaning tool.

Solar panels do need occasional cleaning, though frequency depends on location and weather. Panels that collect dust but see regular rain may only need an annual clean, while dusty, high-bird-traffic areas may need quarterly cleaning.
