Solar suits camping grounds and farm stays well, but only when it is designed around the busiest weekends rather than the average week. A property that sits quiet for most of July and then fills every site over the Easter long weekend needs a very different system from a house with steady daily use. Three things decide the design: hot water in the amenities block, power drawn at powered sites and cabins, and the loads that must keep running when nobody is on site, such as refrigeration, water pressure and security lighting.

Occupancy peaks drive the design

Most rural tourism businesses in NSW see demand bunch up around school holidays, long weekends and local events. Summer peaks line up reasonably well with strong sun, but a Highlands farm stay that is busiest in winter, when guests want warm cabins and long hot showers, faces its heaviest demand in the weakest solar months. Before anyone sizes panels or batteries, pull out your occupancy records for the last two or three years and mark the true peaks.

The gap between peak and off-peak is the reason a hybrid approach is so common. Sizing everything to the busiest weekend of the year leaves a large, expensive battery doing little for months. Sizing to the average leaves guests without hot water exactly when you most need good reviews. The usual answer is solar and storage sized for a solid busy weekend, with a generator or grid connection covering the handful of extreme days. The seasonal load planning guide explains how to build that kind of year-round energy picture.

Amenities blocks: hot water is the biggest load

In most camping grounds, heating water for showers uses more energy than everything else in the amenities block combined. Lighting, exhaust fans and hand dryers matter, but they are small by comparison. How you heat water shapes the whole system.

• Heat pump water heaters commonly use around a quarter to a third of the electricity of a conventional electric element for the same hot water, and they can be timed to run in the middle of the day on solar.
• Solar thermal collectors heat water directly and do well in summer, but still need boosting in winter and during cloudy runs.
• Bottled gas boosting is a practical backstop for off-grid sites on the few days when stored hot water and solar cannot keep up.
• Storage volume matters as much as the heater. Morning and evening shower rushes are short and intense, so a larger insulated tank heated through the day often works better than a bigger heater.

Low-flow shower roses, push-button or timed showers, well insulated pipe runs and motion-sensor LED lighting all reduce the size of the system you need to pay for. Guest laundry machines are best placed on timers, or paired with signage that encourages daytime use.

Powered sites and cabins

Powered sites are where demand becomes hard to predict. A caravan running an air-conditioner, a microwave and an electric kettle at the same time can draw several kilowatts through a single outlet. Multiply that across a full row of sites on a hot January evening and the combined load can exceed what a modest off-grid system can supply.

Grid-connected parks manage this with switchboard capacity and diversity allowances worked out by an electrician. Off-grid sites need clearer rules. Options include offering a limited number of powered sites, restricting outlet ratings on some sites, giving unpowered sites access to a shared charging point for phones and small devices, and stating plainly in your listing that the property runs on solar and what guests can plug in. Cabins are easier to control because you choose the appliances: efficient reverse-cycle air-conditioners, induction or gas cooktops, LED lighting and small, efficient fridges.

Grid, hybrid or fully off-grid?

A farm stay near an existing line has different choices from a bush camp an hour down a dirt road. If the property is already connected, keeping the connection and adding solar and a battery is usually the lowest-risk option, because the grid covers the peaks. Feed-in tariffs in NSW are now commonly a few cents per kWh, far below the 30-45 c/kWh commonly paid for grid electricity, so using solar on site is worth far more than exporting it.

For sites without a connection, a diesel generator is often the existing power source. Used as a primary source, a generator can cost $1,500-$4,000+ a year in fuel alone, before servicing, noise complaints and fuel deliveries. A solar and battery system with the generator relegated to occasional backup typically cuts run hours substantially. The generator versus battery comparison sets out where each still makes sense. For larger or more remote operations, a Generator & Battery Hybrid System is listed on the energy market from $39,900 per site, installed; like every price there, it is indicative and confirmed after a site assessment.

Planning checklist for a tourism property

1. Collect occupancy data, fuel receipts and any power bills for at least two years.
2. List every load by building: amenities blocks, camp kitchen, cabins, office or kiosk, pumps, cool rooms and lighting.
3. Decide how hot water will be heated and how much storage is needed for the morning rush.
4. Set a powered-site policy that the system can actually support.
5. Identify loads that must run when the property is empty, such as refrigeration, water pressure, security lighting and wastewater treatment.
6. Choose secure equipment locations away from guests, children and vehicle movements, with locked enclosures and clear signage.
7. Plan who checks the system during the season and how faults are reported, ideally through remote monitoring.

With that information gathered, each building and load can be sized properly. The system sizing guide walks through daily load, days of autonomy, battery capacity and inverter surge in more detail.

Next steps

A camping ground or farm stay system is only as good as the information behind it. Gather your occupancy records and a list of loads, then request a free assessment from Blue Energy Solar. The assessment happens on site, so amenities blocks, powered sites, roofs, ground space and any existing generator are all looked at before a system is proposed, and the installation and paperwork are handled for you.

Frequently asked questions

Where should the solar panels go on a camping ground?

Roofs of amenities blocks, camp kitchens and machinery sheds are often the first choice because they already exist and keep panels away from guests. If roof space is limited, or shaded by the trees campers love, a ground-mounted array in a fenced area away from vehicle tracks and play areas is common. Structure, orientation and distance to the battery all need checking during a site assessment.

Can the installation be scheduled around the busy season?

Yes, and it should be. Most operators arrange works for quieter months so amenities stay open when guests arrive. Start the assessment and design early, because equipment supply, any network application for a grid-connected site and trenching between buildings all take time. A staged plan can also keep part of the property operating while other sections are connected.

Is remote monitoring worth it for a small farm stay?

For most operators it is. Monitoring shows battery state of charge, solar output, generator run hours and fault alerts on a phone, so you can spot a problem before a guest does. It is especially useful when owners live off site or manage several cabins, and it gives a technician valuable history if something does go wrong.
